Abstract
The efficacy and safety of deep transcranial magnetic stimulation (dTMS) in treating treatment-resistant depression (TRD) are unknown. Up to June 21, 2023, we conducted a systematic search for RCTs, and then extracted and synthesized data using random effects models. Five RCTs involving 507 patients with TRD (243 in the active dTMS group and 264 in the control group) were included in the present study. The active dTMS group showed significantly higher study-defined response rate (45.3% versus 24.2%, n = 507, risk ratio [RR] = 1.87, 95% confidence interval [CI]: 1.21-2.91, I2 = 53%; P = 0.005) and study-defined remission rate (38.3% versus 14.4%, n = 507, RR = 2.37, 95%CI: 1.30-4.32, I2 = 58%; P = 0.005) and superiority in improving depressive symptoms (n = 507, standardized mean difference = -0.65, 95%CI: -1.11--0.18, I2 = 82%; P = 0.006) than the control group. In terms of cognitive functions, no significant differences were observed between the two groups. The two groups also showed similar rates of other adverse events and all-cause discontinuations (P > 0.05). dTMS is an effective and safe treatment strategy for the management of patients with TRD.

Abstract
OBJECTIVES As a novel type of theta burst stimulation (TBS), continuous TBS (cTBS) has been shown to have mixed therapeutic effects for major depressive disorder (MDD) or bipolar depression (BD). Thus, we performed a meta-analysis of randomized controlled trials (RCTs) of cTBS for treating major depressive episodes in patients with MDD or BD. METHODS A systematic search of four major bibliographic databases (PubMed, EMBASE, Cochrane Library, and PsycINFO) was conducted from inception dates to February 3, 2023 to identify eligible studies. The data were analyzed using a random-effects model. RESULTS Three RCTs (n = 78, active cTBS = 37 and sham cTBS = 41) were included the meta-analysis. No significant differences were found in terms of change in Hamilton Depression Rating Scale (HAMD) scores (3 RCTs, n = 78, SMD = -0.09, 95 % CI: -0.53 to 0.36; I2 = 0 %; P = 0.71) and study-defined response (2 RCTs, n = 58, 26.7 % versus 21.4 %, RR = 1.20, 95 % CI: 0.48 to 2.96; I2 = 0 %; P = 0.70) between active and sham cTBS groups. Similarly, no group differences were found in the rates of adverse events and discontinuation due to any reason (P > 0.05). LIMITATIONS Meta-analysis had small sample sizes and low number of included studies. CONCLUSIONS Although cTBS appeared to be a safe and well-tolerated option for treating major depressive episodes in MDD or BD patients, no advantage in treatment effects was found in this meta-analysis. Future large-scale studies are warranted to assess the efficacy of cTBS for MDD or BD patients with a major depressive episode.

Abstract
Objective This systematic review of randomized controlled studies (RCTs) and observational studies evaluated the efficacy and safety of stanford neuromodulation therapy (SNT) for patients with treatment-resistant depression (TRD). Methods A systematic search (up to 25 September, 2023) of RCTs and single-arm prospective studies was conducted. Results One RCT (n = 29) and three single-arm prospective studies (n = 34) met the study entry criteria. In the RCT, compared to sham, active SNT was significantly associated with higher rates of antidepressant response (71.4% versus 13.3%) and remission (57.1% versus 0%). Two out of the three single-arm prospective studies reported the percentage of antidepressant response after completing SNT, ranging from 83.3% (5/6) to 90.5% (19/21). In the three single-arm prospective studies, the antidepressant remission rates ranged from 66.7% (4/6) to 90.5% (19/21). No severe adverse events occurred in all the four studies. Conclusion This systematic review found SNT significantly improved depressive symptoms in patients with TRD within 5 days, without severe adverse events.

Abstract
Objective Intermittent theta-burst stimulation (iTBS), which is a form of repetitive transcranial magnetic stimulation (rTMS), can produce 600 pulses to the left dorsolateral prefrontal cortex (DLPFC) in a stimulation time of just over 3 min. The objective of this systematic review was to compare the safety and efficacy of iTBS and high-frequency (≥ 5 Hz) rTMS (HF-rTMS) for patients with treatment-resistant depression (TRD). Methods Randomized controlled trials (RCTs) comparing the efficacy and safety of iTBS and HF-rTMS were identified by searching English and Chinese databases. The primary outcomes were study-defined response and remission. Results Two RCTs (n = 474) investigating the efficacy and safety of adjunctive iTBS (n = 239) versus HF-rTMS (n = 235) for adult patients with TRD met the inclusion criteria. Among the two included studies (Jadad score = 5), all were classified as high quality. No group differences were found regarding the overall rates of response (iTBS group: 48.0% versus HF-rTMS group: 45.5%) and remission (iTBS group: 30.0% versus HF-rTMS group: 25.2%; all Ps > 0.05). The rates of discontinuation and adverse events such as headache were similar between the two groups (all Ps > 0.05). Conclusion The antidepressant effects and safety of iTBS and HF-rTMS appeared to be similar for patients with TRD, although additional RCTs with rigorous methodology are needed.

Abstract
We aimed to systematically evaluate the clinical efficacy and safety of accelerated intermittent theta burst stimulation (aiTBS) for patients with major depressive disorder (MDD) or bipolar depression (BD). A random-effects model was adopted to analyze the primary and secondary outcomes using the Review Manager, Version 5.3 software. This meta-analysis (MA) identified five double-blind randomized controlled trials (RCTs) comprising 239 MDD or BD patients with a major depressive episode. Active aiTBS overperformed sham stimulation in the study-defined response. This MA found preliminary evidence that active aiTBS resulted in a greater response in treating major depressive episodes in MDD or BD patients than sham stimulation.

Abstract
Objective We performed a meta-analysis of randomized, double-blind, controlled trials (RCTs) to systematically investigate the therapeutic effects and tolerability of transcranial alternating current stimulation (tACS) for the treatment of patients with major depressive disorder (MDD). Methods Electronic search of PubMed, PsycINFO, EMBASE, Chinese National Knowledge Infrastructure, Wanfang database, and the Cochrane Library up to 1 April 2022. Double-blind RCTs examining the efficacy and safety of tACS for patients with MDD were included. The primary outcome was the improvement of depressive symptoms following a course of tACS treatment. Data were analyzed using Review Manager Version 5.3 (Cochrane IMS, Oxford, UK). Study quality was assessed using the Cochrane risk of bias and Jadad scale. Publication bias was assessed using a funnel plot and the Egger test. Results We identified 883 articles, of which 4 RCTs with 5 active treatment arms covering 224 participants with MDD on active tACS (n = 117) and sham tACS (n = 107) were eligible for inclusion. Meta-analysis of depressive symptoms at post-tACS found an advantage of active tACS over sham tACS (n = 212, standard mean difference (SMD) = -1.14, 95% confidence interval (CI): -2.23, -0.06; I 2 = 90%, P = 0.04). The significant superiority of active tACS over sham tACS in improving depressive symptoms remained in a sensitivity analysis. Active tACS was significantly superior to sham tACS regarding depressive symptoms at the 4 week follow-up (SMD = -1.07, 95% CI: -2.05, -0.08; I 2 = 88%, P = 0.03) and study-defined remission [risk ratio (RR) = 2.07, 95% CI: 1.36, 3.14, I 2 = 9%, P = 0.0006]. The discontinuation rate due to any reason was similar between the two groups (P > 0.05). All included studies were rated as high quality (Jadad score ≥ 3), with funnel plots of primary outcome not suggestive of publication bias. Conclusion tACS appeared to be modestly effective and safe for improving depressive symptoms in patients with MDD, although further studies are warranted.

Abstract
Schizophrenia is associated with an increased risk of metabolic syndrome (MetS), which is an important risk factor for developing cognitive impairment in the general population. A few case-control studies have explored the relationship between MetS and cognitive deficits in individuals with schizophrenia but with inconsistent findings. This meta-analysis of case-control studies was carried out to explore the association between MetS and cognitive performance in patients with schizophrenia. Only case-control studies assessing the association of cognitive function and MetS in patients with schizophrenia were identified. Cognitive function was assessed using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) scale. Six case-control studies (n = 992) comparing cognition between patients with schizophrenia with MetS (n = 426) and those without MetS (n = 566) using the RBANS were identified. Compared to patients with schizophrenia without MetS, patients with schizophrenia and MetS had significantly more impairments in RBANS total scores [standardized mean difference (SMD) = -0.26, 95% confidence interval (CI): -0.51 to -0.02; I2 = 72%; p = 0.03], immediate memory (SMD = -0.32, 95% CI: -0.54 to -0.10; I2 = 66%; p = 0.005), attention (SMD = -0.29, 95% CI: -0.56 to -0.02; I2 = 77%; p = 0.03), and delayed memory (SMD = -0.24, 95% CI: -0.46 to -0.03; I2 = 64%; p = 0.03). No group difference was found regarding visuospatial skills and language (p > 0.05). This meta-analysis found that schizophrenia patients with MetS had worse performance on certain cognitive tasks than non-MetS patients.

Abstract
Findings of multi-session transcranial direct current stimulation (tDCS) as an adjunctive treatment of neurocognitive dysfunction in schizophrenia have been inconsistent. This meta-analysis of randomized controlled trials (RCTs) investigated the neurocognitive effects of adjunctive multi-session tDCS for schizophrenia. Twelve RCTs covering 418 schizophrenia patients were included and analyzed in this meta-analysis. The RevMan software (Version 5.3) was used to calculate risk ratios (RRs) and standardized mean differences (SMDs) with their 95% confidence intervals (CIs). Adjunctive tDCS outperformed the comparator in improving working memory deficits (SMD = 0.34, 95% CI: 0.03, 0.65; I2 = 52%; p = 0.03), but no significant effects were found in other cognitive domains. No group differences were found with regard to total psychopathology measured by the Brief Psychiatric Rating Scale and the Positive and Negative Symptom Scale (SMD =-0.29, 95%CI: -0.61, 0.03; I2 = 50%, p = 0.07) and discontinuation due to any reason (RR=0.80, 95%CI: 0.39, 1.66; I2 = 9%, p = 0.56). Adjunctive tDCS appears to have a significant therapeutic effect improving the working memory deficits in schizophrenia.

Abstract
Objective: The efficacy and safety of adjunctive magnetic seizure therapy (MST) for patients with schizophrenia are unclear. This systematic review was conducted to examine the efficacy and safety of adjunctive MST for schizophrenia. Methods: Chinese (WanFang and Chinese Journal Net) and English (PubMed, EMBASE, PsycINFO, and the Cochrane Library) databases were systematically searched. Results: Two open-label self-controlled studies (n = 16) were included and analyzed in this review. In these studies, the Positive and Negative Syndrome Scale (PANSS) total scores and Brief Psychiatric Rating Scale (BPRS) total scores significantly decreased from baseline to post-MST (all Ps < 0.05), without serious adverse neurocognitive effects. Mixed findings on the neurocognitive effects of adjunctive MST for schizophrenia were reported in the two studies. A discontinuation rate of treatment of up to 50% (4/8) was reported in both studies. The rate of adverse drug reactions (ADRs) was evaluated in only one study, where the most common ADRs were found to be dizziness (25%, 2/8) and subjective memory loss (12.5%, 1/8). Conclusion: There is inconsistent evidence for MST-related adverse neurocognitive effects and preliminary evidence for the alleviation of psychotic symptoms in schizophrenia.

Abstract
Aripiprazole, metformin, and paeoniae-glycyrrhiza decoction (PGD) have been widely used as adjunctive treatments to reduce antipsychotic (AP)-induced hyperprolactinemia in patients with schizophrenia. However, the comparative efficacy and safety of these medications have not been previously studied. A network meta-analysis of randomized controlled trials (RCTs) was conducted to compare the efficacy and safety between aripiprazole, metformin, and PGD as adjunctive medications in reducing AP-induced hyperprolactinemia in schizophrenia. Both international (PubMed, PsycINFO, EMBASE, and Cochrane Library databases) and Chinese (WanFang, Chinese Biomedical, and Chinese National Knowledge infrastructure) databases were searched from their inception until January 3, 2019. Data were analyzed using the Bayesian Markov Chain Monte Carlo simulations with the WinBUGS software. A total of 62 RCTs with 5,550 participants were included in the meta-analysis. Of the nine groups of treatments included, adjunctive aripiprazole (<5 mg/day) was associated with the most significant reduction in prolactin levels compared to placebo (posterior MD = -65.52, 95% CI = -104.91, -24.08) and the other eight treatment groups. Moreover, adjunctive PGD (>1:1) was associated with the lowest rate of all-cause discontinuation compared to placebo (posterior odds ratio = 0.45, 95% CI = 0.10, 3.13) and adjunctive aripiprazole (>10 mg/day) was associated with fewer total adverse drug events than placebo (posterior OR = 0.93, 95% CI = 0.65, 1.77) and other eight treatment groups. In addition, when risperidone, amisulpride, and olanzapine were the primary AP medications, adjunctive paeoniae/glycyrrhiza = 1:1, aripiprazole <5 mg/day, and aripiprazole >10 mg/day were the most effective treatments in reducing the prolactin levels, respectively. Adjunctive aripiprazole, metformin, and PGD showed beneficial effects in reducing AP-induced hyperprolactinemia in schizophrenia, with aripiprazole (<5 mg/day) being the most effective one.

Abstract
Neuroinflammation appears to be associated with the neurobiology of depression, and treatments targeting inflammation have shown promising results in depression. This meta-analysis examined the efficacy and safety of minocycline, an anti-inflammatory drug, for the treatment of depressive symptoms. A systematic electronic literature search was independently conducted by two investigators. Standardized mean differences (SMDs) and risk ratio (RR) with their 95% confidence interval (CI) were calculated using a random-effect model. Four RCTs (n = 211) were identified for meta-analysis. Minocycline showed a significant trend of improvement in depressive symptoms compared to placebo [4 RCTs, n = 190, SMD: -0.54 (95%CI:-1.12, 0.04), P = 0.07; I2 = 73%]. Subgroup analyses showed that minocycline was superior to placebo in improving depressive symptoms in studies of unipolar depression (3 RCTs, n = 151, SMD: -0.77 (95%CI:-1.32, -0.22), P = 0.006; I2 = 60%) and in studies using minocycline monotherapy [SMD: -1.06 (95%CI:-1.68, -0.44), P = 0.0008]. The rates of discontinuation due to any reasons [RR: 1.48 (95%CI: 0.79, 2.77), P = 0.22, I2 = 0%] and adverse drug reactions [RR: 0.32 to 1.98 (95%CI: 0.03, 14.74), P = 0.19 to 0.84, I2 = 0% to 31%] were similar between minocycline and placebo. Minocycline appears to be effective and well-tolerated in ameliorating depressive symptoms in unipolar depression. Future large RCTs with sufficient duration is needed to confirm the positive effects of minocycline in treating depressive symptoms.

Abstract
Antipsychotic-induced dyslipidemia could increase the risk of cardiovascular diseases. This is a meta-analysis of randomized double-blind placebo-controlled trials to examine the efficacy and safety of adjunctive metformin for dyslipidemia induced by antipsychotics in schizophrenia. The standardized mean differences (SMDs) and risk ratios (RRs) with their 95% confidence intervals (CIs) were calculated using the random-effects model with the RevMan 5.3 version software. The primary outcome was the change of serum lipid level. Twelve studies with 1215 schizophrenia patients (592 in metformin group and 623 in placebo group) were included and analyzed. Adjunctive metformin was significantly superior to placebo with regards to low density lipoprotein cholesterol (LDL-C) [SMD: -0.37 (95%CI:-0.69, -0.05), P = 0.02; I2 = 78%], total cholesterol [SMD: -0.47 (95%CI:-0.66, -0.29), P < 0.00001; I2 = 49%], triglyceride [SMD: -0.33 (95%CI:-0.45, -0.20), P < 0.00001; I2 = 0%], and high density lipoprotein cholesterol [SMD: 0.29 (95%CI:0.02, 0.57), P = 0.03; I2 = 69%]. The superiority of metformin in improving LDL-C level disappeared in a sensitivity analysis and 80% (8/10) of subgroup analyses. Metformin was significantly superior to placebo with regards to decrease in body weight, body mass index, glycated hemoglobin A1c, fasting insulin, and homeostasis model assessment-insulin resistance (P = 0.002-0.01), but not regarding changes in waist circumference, waist-to-hip rate, leptin, fasting glucose, and blood pressure (P = 0.07-0.33). The rates of discontinuation due to any reason [RR: 0.97 (95%CI: 0.66, 1.43), P = 0.89; I2 = 0%] was similar between the two groups. Adjunctive metformin could be useful to improve total cholesterol and triglyceride levels, but it was not effective in improving LDL-C level in schizophrenia.

Abstract
BACKGROUND Lipid profile disturbances are frequently observed in major depressive disorder (MDD) and constitute to high mortality rates. However, less is known about whether this risk is present in patients with first-episode MDD. Therefore, this meta-analysis was conducted to examine if lipid parameters differed between healthy controls and first-episode MDD patients. METHODS Cochrane Library, PubMed, PsycINFO, EMBASE, Chinese Journal Net, and WanFang databases were searched from inception to October 23, 2018. The primary outcomes were triglycerides, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and total cholesterol levels. RESULTS A total of 11 case-control studies compared 690 subjects with first-episode MDD and 614 healthy controls were included and analyzed. Compared to healthy controls, patients with first-episode MDD were significantly associated with higher triglyceride (SMD = 0.29, 95% CI: 0.09, 0.48, P = 0.004) and lower HDL cholesterol levels (SMD = -0.54, 95% CI: -0.86, -0.22, P = 0.001). Subgroup analyses revealed that first-episode MDD patients with higher triglyceride and lower HDL levels were found only in Chinese and plasma group when compared to healthy controls (P < 0.05). Meta-regression analysis showed that the significant heterogeneity for triglyceride and HDL cholesterol was partly explained by the quality of study. No significant difference was found in LDL cholesterol and total cholesterol levels between the two groups. LIMITATIONS Heterogeneity was relatively high among the included studies. CONCLUSIONS Elevated triglyceride and decreased HDL cholesterol levels may be associated with first-episode MDD. Findings support early lipid monitoring and interventions targeting healthy lifestyle.

Abstract
OBJECTIVES This is a meta-analysis of randomized double-blind controlled-placebo trials (RCTs) examining the effectiveness, tolerability, and safety of intranasal esketamine in treating major depressive disorder (MDD). METHODS Standardized mean difference (SMD), risk ratio (RR) and their 95% confidence intervals (CIs) were calculated using RevMan version 5.3. RESULTS Four RCTs with 7 active arms covering 708 patients with MDD on intranasal esketamine (n = 419) and placebo (n = 289) were included. Compared with placebo, adjunctive intranasal esketamine was associated with significantly greater study-defined response (RR=1.39, 95%CI: 1.18 to 1.64, P<0.0001) and remission (RR=1.42, 95%CI: 1.17 to 1.72, P = 0.0004) at endpoint assessment. Intranasal esketamine had greater study-defined response starting at 2 h (RR= 2.77, 95%CI: 1.62 to 4.76, P = 0.0002), peaking at 24 h (RR=5.42, 95%CI: 1.38 to 21.20, P = 0.02), and at least lasting for 28 days (RR=1.36, 95%CI: 1.16 to 1.58, P = 0.0001). Similarly, intranasal esketamine had significantly greater study-defined remission starting at 2 h (RR=7.71, 95%CI: 2.16 to 27.55, P = 0.002), peaking at 24 h (RR=6.87, 95%CI: 1.55 to 30.35, P = 0.01), and lasting for 28 days (RR=1.38, 95%CI: 1.11 to 1.72, P = 0.004). Intranasal esketamine had a significantly higher rate of discontinuation due to intolerability (RR=3.50, 95%CI: 1.38 to 8.86, P = 0.008). Discontinuation due to any reasons and inefficacy were similar between the two groups. CONCLUSION Intranasal esketamine appears to have an ultra-rapid antidepressant effect for MDD, at least lasting for 28 days. The long-term therapeutic effect and safety of intranasal esketamine need to be further examined in large-scale RCTs.

Abstract
Background Hyperprolactinaemia is a common antipsychotic (AP)-induced adverse effect, particularly in female patients. Aims This meta-analysis examined the efficacy and safety of adjunctive aripiprazole in preventing AP-related hyperprolactinaemia in patients with first-episode schizophrenia. Methods PubMed, PsycINFO, EMBASE, Cochrane Library, WanFang and China Journal Net databases were searched to identify eligible randomised controlled trials (RCTs). Primary outcomes were the reductions of serum prolactin level and prolactin-related symptoms. Data were independently extracted by two reviewers and analysed using RevMan (V.5.3). Weighted/standardised mean differences (WMDs/SMDs)±95% CIs were reported. Results In the five RCTs (n=400), the adjunctive aripiprazole (n=197) and the control groups (n=203) with a mean of 11.2 weeks of treatment duration were compared. The aripiprazole group had a significantly lower endpoint serum prolactin level in all patients (five RCTs, n=385; WMD: −50.43 ng/mL (95% CI: −75.05 to −25.81), p<0.00001; I2=99%), female patients (two RCTs, n=186; WMD: −22.58 ng/mL (95% CI: −25.67 to −19.49), p<0.00001; I2=0%) and male patients (two RCTs, n=127; WMD: −68.80 ng/mL (95% CI: −100.11 to −37.49), p<0.0001). In the sensitivity analysis for the endpoint serum prolactin level in all patients, the findings remained significant (p<0.00001; I2=96%). The aripiprazole group was superior to the control group in improving negative symptoms as assessed by the Positive and Negative Syndrome Scale (three RCTs, n=213; SMD: −0.51 (95% CI: −0.79 to −0.24), p=0.0002; I2=0%). Adverse effects and discontinuation rates were similar between the two groups. Conclusions Adjunctive aripiprazole appears to be associated with reduced AP-induced hyperprolactinaemia and improved prolactin-related symptoms in first-episode schizophrenia. Further studies with large sample sizes are needed to confirm these findings.

Abstract
OBJECTIVES This meta-analysis of randomized controlled trials (RCTs) examined the efficacy and safety of minocycline for three major mental disorders: schizophrenia, bipolar disorder and major depressive disorder (MDD). METHODS A systematic literature search of major electronic databases was conducted. Meta-analysis of clinical efficacy as defined by the respective studies, all-cause discontinuation, adverse drug reactions (ADRs) with standardized mean difference (SMD) and risk ratios (RRs) and their 95% confidence intervals (CI) was conducted using random-effects model. Quality assessment was performed with the Jadad scale and Cochrane risk of bias. RESULTS Sixteen RCTs (n=1357) on minocycline (50-300 mg/day) for schizophrenia (13 RCTs, n=1196), bipolar depression (1 RCT, n=49), and MDD (2 RCTs, n=112) were analyzed separately by diagnosis. Twelve RCTs mentioned randomized allocation specifically; the weighted Jadad scores were 4.0. Adjunctive minocycline outperformed placebo in improving total psychopathology [SMD: -0.45 (95%CI: -0.73, -0.16), p=0.002; I2=77%], positive [SMD: -0.15 (95%CI: -0.28, -0.02), p=0.02; I2=0%], negative [SMD: -0.62 (95%CI: -0.95, -0.28), p=0.0003; I2=85%] and general psychopathology scores [SMD: -0.28 (95%CI: -0.53, -0.03), p=0.03; I2=59%] in schizophrenia. Minocycline showed no significant effect on depressive and manic symptoms in both bipolar depression and MDD. Minocycline caused significantly less headache (p=0.02, number-needed-to-harm=14, 95%CI=5-14) than placebo in schizophrenia. All-cause discontinuation and other ADRs were similar between minocycline and placebo in each diagnostic category. CONCLUSION In this meta-analysis, adjunctive minocycline appeared to be efficacious and safe for schizophrenia. However, the efficacy of adjunctive minocycline for bipolar depression or MDD could not be demonstrated. REVIEW REGISTRATION PROSPERO: CRD42018102483.

Abstract
OBJECTIVES To systematically examine the effectiveness, tolerability, and safety of brexanolone infusion in treating postpartum depression (PPD). METHODS Randomized controlled trials (RCTs) were included. RESULTS Two articles reporting 3 RCTs with 4 active arms (n = 267) covering 156 women with PPD receiving brexanolone infusion and 111 women with PPD on placebo were included. Compared with placebo, women suffering from PPD who received brexanolone had significantly greater response that started after 24 h (risk ratio (RR)=1.34, 95%CI 1.03-1.73), peaked at 36 h (RR = 1.50, 95%CI 1.06-2.13, P = 0.02) and lasted until Day 7 (RR = 1.32, 95%CI 1.01-1.73). Similarly, PPD women treated with brexanolone had significantly greater remission starting at 24 h (RR = 1.86, 95%CI 1.03-3.34), peaking at 60 h (RR = 2.20, 95%CI 1.31-3.70) and lasting until 72 h (RR = 1.96, 95%CI 1.41-2.72). Brexanolone infusion led to significantly higher rate of discontinuation for any reasons (RR = 2.68, 95%CI 1.35-5.32). Discontinuation due to intolerability and adverse drug reactions was similar between the active agent and placebo. CONCLUSION A single brexanolone infusion appears to have ultra-rapid antidepressant effect for PPD, lasting for up to 1 week. The short and long-term therapeutic effect of brexanolone needs to be examined in large-scale RCTs.

Abstract
OBJECTIVE As a non-competitive N-methyl-d-aspartate receptor antagonist, memantine has been used to treat major mental disorders including schizophrenia, bipolar disorder, and major depressive disorder (MDD). This meta-analysis systematically investigated the effectiveness and tolerability of adjunctive memantine for patients with schizophrenia, bipolar disorder, and MDD. METHODS Only randomized controlled trials (RCTs) were identified and included in the study. Data of the three disorders were separately synthesized using the RevMan 5.3 software. RESULTS Fifteen RCTs (n = 988) examining memantine (5-20 mg/day) as an adjunct treatment for schizophrenia (9 trials with 512 patients), bipolar disorder (3 trials with 319 patients), and MDD (3 trials with 157 patients) were analyzed. Memantine outperformed the comparator regarding total psychopathology with a standardized mean difference (SMD) of -0.56 [95% confidence interval (CI): -1.01, -0.11; I2 = 76%, P = 0.01] and negative symptoms with an SMD of -0.71 (95% CI: -1.09, -0.33; I2 = 74%, P = 0.0003) in schizophrenia, but no significant effects were found with regard to positive symptoms and general psychopathology in schizophrenia, or depressive and manic symptoms in bipolar disorder or depressive symptoms in MDD. Memantine outperformed the comparator in improving cognitive performance in schizophrenia with an SMD of 1.07 (95% CI: 0.53, 1.61; P < 0.0001, I2 = 29%). No group differences were found in the rates of adverse drug reactions and discontinuation due to any reason in the three major mental disorders. CONCLUSIONS Memantine as an adjunct treatment appears to have significant efficacy in improving negative symptoms in schizophrenia. The efficacy and safety of adjunctive memantine for bipolar disorder or MDD needs to be further examined. REVIEW REGISTRATION PROSPERO: 42018099045.

Abstract
BACKGROUND Results of previous studies on the safety and efficacy of adjunctive reboxetine for schizophrenia have been inconsistent. AIM The aim of this study was to examine the efficacy and tolerability of reboxetine as an adjunct medication to antipsychotic treatment in a meta-analysis of randomized controlled trials (RCTs). METHODS Two independent investigators extracted data for a random effects meta-analysis and assessed the quality of studies using risk of bias and the Jadad scale. Weighted and standardized mean differences (WMDs/SMDs) and risk ratio (RR)±95% confidence intervals (CIs) were calculated. RESULTS Nine RCTs (n=630) with double-blind design were identified. Reboxetine outperformed placebo in improving negative (9 RCTs, n=602, SMD: -0.47 [95% CI: -0.87, -0.07], p=0.02; I2=82%), but not the overall, positive, and general psychopathology scores. The significant therapeutic effect on negative symptoms disappeared in the sensitivity analysis after removing an outlying study and in 50% (6/12) of the subgroup analyses. Reboxetine outperformed placebo in reducing weight (3 RCTs, n=186, WMD: -3.83 kg, p=0.04; I2=92%) and body mass index (WMD: -2.23 kg/m2, p=0.04; I2=95%). Reboxetine caused dry mouth but was associated with less weight gain overall and weight gain of ≥7% of the initial weight. All-cause discontinuation and other adverse events were similar between reboxetine and placebo. CONCLUSION Adjunctive reboxetine could be useful for attenuating antipsychotic-induced weight gain, but it was not effective in treating psychopathology including negative symptoms in schizophrenia.

Abstract
BACKGROUND Adjunctive ketamine with electroconvulsive therapy (ECT) has been investigated for treating major depressive disorder (MDD), but the findings have been inconsistent. AIM This is an updated meta-analysis of the efficacy and safety of ketamine augmentation of ECT in the treatment of MDD. METHODS Randomized controlled trials (RCTs) reporting on the efficacy and safety of ketamine and ECT were identified and analyzed. RESULTS Seventeen RCTs (n = 1,035) compared ketamine alone or ketamine plus other anesthetic drugs (n = 557) with other anesthetic agents (n = 478) in MDD patients who received ECT. Ketamine+other anesthetic drugs was superior in improving depressive symptoms over other anesthetic medications at early study time point, but not at post-ECT or end of study time points. Ketamine alone was not more efficacious in treating depressive symptoms than other anesthetic drugs at early study, post-ECT and end of study time points. Sensitivity analysis and 19 of the 20 subgroup analyses also confirmed the lack of significance of these findings. Eleven RCTs testing the effects of ketamine on neurocognitive functions with various test batteries found mixed results. Ketamine alone significantly increased blood pressure more than other anesthetic drugs in MDD treated with ECT. CONCLUSION Compared to other anesthetic agents, ketamine alone does not appear to improve the efficacy of ECT. However, ketamine+other anesthetic combinations may confer a short-term advantage in improving depressive symptom at the early stages of ECT.

Abstract
BACKGROUND Hyperprolactinaemia is a common adverse effect of antipsychotics (APs). The results of Peony-Glycyrrhiza decoction (PGD) as a potentially useful adjunctive treatment for hyperprolactinaemia are inconsistent. AIM This meta-analysis of randomised controlled trials (RCTs) examined the efficacy and safety of adjunctive PGD therapy for AP-induced hyperprolactinaemia. METHODS English (PubMed, Embase, Cochrane Library, PsycINFO) and Chinese (Chinese National Knowledge Infrastructure, Wanfang Data) databases were systematically searched up to 10 June 2018. The inclusion criteria were based on PICOS-Participants: adult patients with schizophrenia; Intervention: PGD plus APs; Comparison: APs plus placebo or AP monotherapy; Outcomes: efficacy and safety; Study design: RCTs. The weighted mean difference (WMD) and risk ratio (RR) along with their 95% CIs were calculated using Review Manager (RevMan) V.5.3 software. RESULTS Five RCTs (n=450) were included and analysed. Two RCTs (n=140) were double-blind and four RCTs (n=409) reported 'random' assignment with specific description. The PGD group showed a significantly lower serum prolactin level at endpoint than the control group (n=380, WMD: -32.69 ng/mL (95% CI -41.66 to 23.72), p<0.00001, I 2 =97%). Similarly, the superiority of PGD over the control groups was also found in the improvement of hyperprolactinaemia-related symptoms. No difference was found in the improvement of psychiatric symptoms assessed by the Positive and Negative Syndrome Scale (n=403, WMD: -0.62 (95% CI -2.38 to 1.15), p=0.49, I 2 =0%). There were similar rates of all-cause discontinuation (n=330, RR 0.93 (95% CI 0.63 to 1.37), p=0.71, I 2 =0%) and adverse drug reactions between the two groups. According to the Grading of Recommendations Assessment, Development and Evaluation approach, the level of evidence of primary and secondary outcomes ranged from 'very low' (14.3%), 'low' (42.8%), 'moderate' (14.3%), to 'high' (28.6%). CONCLUSIONS Current evidence supports the adjunctive use of PGD to suppress elevated prolactin and improve prolactin-induced symptoms without significant adverse events in adult patients with AP-induced hyperprolactinaemia. High-quality RCTs with longer duration are needed to confirm these findings. TRIAL REGISTRATION NUMBER 42016037017.

Abstract
Findings of neurocognitive dysfunction in subjects at Clinical High Risk for Psychosis (CHR-P) have been controversial. This meta-analysis systematically examined studies of neurocognitive functions using the MATRICS Consensus Cognitive Battery (MCCB) in CHR-P. An independent literature search of both English and Chinese databases was conducted by two reviewers. Standardized mean difference (SMD) was calculated using a random effects model to evaluate the effect size of the meta-analytic results. Six case-control studies (n = 396) comparing neurocognitive functions between CHR-P subjects (n = 197) and healthy controls (n = 199) using the MCCB were identified; 4 (66.7%) studies were rated as "high quality". Compared to healthy controls, CHR-P subjects showed impairment with large effect size in overall cognition (n = 128, SMD = -1.00, 95%CI: -1.38, -0.63, P < 0.00001; I2 = 2%), processing speed (SMD = -1.21) and attention/vigilance (SMD = -0.83), and with medium effect size in working memory (SMD = -0.76), reasoning and problem solving (SMD = -0.71), visual (SMD = -0.68) and verbal learning (SMD = -0.67). No significant difference between CHR-P subjects and controls was found regarding social cognition (SMD = -0.33, 95%CI: -0.76, 0.10, P = 0.14; I2 = 70%) with small effect size. Apart from social cognition, CHR-P subjects performed worse than healthy control in all MCCB cognitive domains, particularly in processing speed, attention/vigilance and working memory.

Abstract
BACKGROUND Lurasidone, an azapirone derivative, is a novel second generation antipsychotic with potent binding affinity for dopamine D2, serotonin 5-HT2A, 5-HT7, 5-HT1A, and noradrenaline alpha2C receptors. This updated meta-analysis of randomized controlled trials (RCTs) examined the short-term efficacy and tolerability of lurasidone in the treatment of acute schizophrenia. METHODS Double-blinded RCTs reporting on the short-term effects of lurasidone were included. Standardized mean difference (SMD) with their 95% confidence interval (CI), and number needed to harm (NNH) were computed. RESULTS The meta-analysis had 8 RCTs with 16 active arms that included 2373 patients with acute schizophrenia who were randomized to either lurasidone (20-160 mg/day; n = 1570) or placebo (n = 803) groups. Lurasidone was superior to placebo with regard to change in total psychopathology [SMD: -0.34, (95%CI: -0.48, -0.20), P<0.00001], positive symptoms [SMD: -0.47, (95%CI: -0.57, -0.36), P<0.00001], negative symptoms [SMD:-0.34, (95%CI: -0.45, -0.22), P<0.00001], and general psychopathology [SMD: -0.36, (95%CI: -0.48, -0.24), P<0.00001]. Results were consistent for total psychopathology in 11 out of the 13 subgroups. Lurasidone resulted in higher weight gain [SMD: 0.15, (95% CI: 0.06, 0.24), P = 0.001] and BMI [SMD: 0.17, (95%CI: 0.07, 0.28), P = 0.002] than placebo, but the differences were not clinically significant. Lurasidone group had less frequent inefficacy (NNH = 14) and discontinuation due to any reason (NNH = 17), but was associated with more frequent vomiting, akathisia, dystonia, parkinsonism, somnolence, dizziness, sedation, nausea, and weight gain of ≥7% of the initial weight (NNH = 11-50). CONCLUSION This meta-analysis of 8 short-term studies supported the efficacy and safety of lurasidone in the acute phase of schizophrenia, particularly at the higher dose range of 80 mg/day.

Abstract
OBJECTIVE Raloxifene, a selective estrogen receptor modulator, has been used in treating postmenopausal women with schizophrenia with inconsistent results. This meta-analysis of randomized, double-blind, placebo-controlled trials (RCTs) examined its efficacy and safety for postmenopausal women with schizophrenia. METHOD Standardized mean differences (SMDs) and risk ratio (RR) together with their 95% confidence intervals (CIs) were calculated using the random effects model. RESULTS The meta-analysis included 5 RCTs (n = 240) comparing raloxifene (n = 125, 60 or 120 mg/day) with placebo (n = 115). Adjunctive raloxifene outperformed placebo with regard to the Positive and Negative Syndrome Scale (PANSS) total psychopathology [n = 240, SMD:-0.64 (95%CI:-0.90, -0.37), P < 0.00001; I2 = 0%], positive symptoms [n = 240, SMD:-0.49 (95%CI:-0.81, -0.16), P = 0.003; I2 = 29%], negative symptoms [n = 240, SMD:-0.43 (95%CI:-0.68, -0.17), P = 0.001; I2 = 0%], and general psychopathology scores [n = 240, SMD:-0.66 (95%CI:-0.92, -0.39), P < 0.00001; I2 = 0%]. Both groups had similar rates of adverse events and discontinuation (n = 159, RR: 1.32 (95%CI: 0.65, 2.70), P = 0.44, I2 = 0%). CONCLUSION Adjunctive raloxifene appears to be effective and safe in improving psychotic symptoms for postmenopausal women with schizophrenia. Review registration: CRD 42017059946.

Abstract
INTRODUCTION Weight gain is a common antipsychotic (AP)-related adverse drug reaction (ADR) that can increase the risk of cardiovascular diseases and premature mortality. This meta-analysis examined the efficacy and tolerability of combining metformin and lifestyle intervention for AP-related weight gain in schizophrenia. METHODS Randomized controlled trials (RCTs) with meta-analyzable data were searched and retrieved by 2 independent investigators. RevMan software (version 5.3) was used to synthesize data, and to calculate the standardized or weighted mean differences and risk ratio with their 95% confidence intervals. RESULTS Six RCTs (n=732) were included and meta-analyzed. The metformin and lifestyle combination (MLC) group had significant reduction in weight and body mass index compared with the metformin group, lifestyle group, and placebo group. There was less frequent weight gain of≥7% in the MLC group over placebo. No other group differences in ADRs, total psychopathology, and all-cause discontinuation were found. In terms of study quality, 5 RCTs were open-labelled, 1 RCT had low risk allocation concealment, and 3 RCTs specifically described randomization methods. CONCLUSION Combining metformin and lifestyle intervention shows significant effect in reducing AP-related weight gain. Higher quality and larger RCTs are needed to confirm these findings.Review registration: CRD42017059198.

Abstract
Background Metabolic syndrome in patients with schizophrenia is a major health concern. The efficacy and safety of adjunctive rosuvastatin in treating dyslipidemia were controversial. Aims To assess the efficacy and safety of adjunctive rosuvastatin for dyslipidemia in patients with schizophrenia. Methods We systematically searched for relevant controlled clinical trials from the following databases: PubMed, PsycINFO, Cochrane Library, China Knowledge Network, WanFang Database and Chinese Biomedical Database up to September 28, 2017. Standardized mean difference (SMD) and risk ratio (RR) along with their 95% confidence intervals (CIs) were calculated. The quality of the included studies was assessed using the Cochrane risk of bias assessment tool. The GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) system recommendation grading method was used as the reference standard. Results Four studies (n=274) comparing rosuvastatin (n=138) and control (n=136) groups were identified and analyzed. Adjunctive rosuvastatin showed greater efficacy than control group in low density lipoprotein cholesterol (LDL-C) [4 trials, n=272, SMD: -1.31 (95%CI: -1.93, -0.70), I2=81%], total cholesterol (2 trials, n=164, SMD: -2.00 (95%CI: -2.79, -1.21); I2=76%) and triglycerides (2 trials, n=164, SMD: -1.05 (95%CI: -1.38, -0.72); I2=0%), but not in high density lipoprotein cholesterol (2 trials, n=164, SMD: 0.14 (95%CI: -0.16, 0.45); I2=0%). After removing one study without randomization for LDL-C, significance remained [3 trials, n=172, SMD:-1.07 (95%CI: -1.60, -0.53); I2=63%]. No significant group differences regarding body weight (3 trials, n=208, SMD: -0.40 (95%CI:-1.29, 0.49); I2=89%), body mass index (2 trials, n=164, SMD: -0.34 (95%CI: -1.23, 0.56); I2=87%), waist circumference (3 trials, n=208, SMD): -0.43 (95%CI: -1.31, 0.46); I2=89%), and fasting glucose (4 trials, n=272, SMD: -0.25 (95%CI: -0.65, 0.15); I2=62%) were observed. The adverse reactions and any cause discontinuation rate were similar between the groups. According to the GRADE approach, the evidence levels of main outcomes were rated as “very low” (35.3%) to “low” (64.7%). Of them, the primary outcome (LDL-C) was rated as “very low “. Conclusions The data available on the effectiveness and safety of adjunctive rosuvastatin in treating dyslipidemia for patients with schizophrenia is insufficient to come to a definitive interpretation about its efficacy and safety. Further high quality RCTs with extended treatment duration are warranted to confirm the findings. Review registration PROSPERO: CRD42017078230

Abstract
Azapirones, which are serotonin1A (5-HT1A) receptor partial agonists, have been used as an adjunctive treatment for schizophrenia with mixed results. This is a meta-analysis of the efficacy and tolerability of azapirones for schizophrenia based on randomized, double-blind, placebo-controlled trials (RCTs). English and Chinese databases were systematically and independently searched by two investigators. Data were extracted and analyzed using the RevMan software (version 5.3). Seven RCTs (n = 368) of azapirones (buspirone in 6 RCTs and tandospirone in 1 RCT) were identified and analyzed. Only adjunctive buspirone outperformed placebo regarding total psychopathology [standardized mean difference: -1.03 (95% confidence interval (CI): -1.91, -0.15), P = 0.02; I2 = 92%], but the significance disappeared in sensitivity analysis after removing two outlying studies, and in 10 of the 12 subgroup analyses. In 5 RCTs examining neurocognitive function of azapirones, only 2 RCTs found the superiority of buspirone in improving attention/speeded motor performance, verbal and performance intelligence. Adjunctive buspirone outperformed placebo regarding extrapyramidal symptoms [SMD:-0.51, (95%CI: -0.99, -0.02), P = 0.04; I2 = 0%]. Similar rates of discontinuation [risk ratio:1.06 (95%CI:0.54, 2.07), P = 0.86, I2 = 0%] and adverse drug reactions were found between both groups. Adjunctive buspirone and tandospirone failed to show efficacy for psychotic symptoms, but adjunctive buspirone may be associated with improvement in extrapyramidal symptoms and cognitive deficits in schizophrenia. Due to the preliminary nature of this meta-analysis, larger sample size and higher quality RCTs are needed to confirm these finding.

Abstract
UNLABELLED Neuroinflammation has been implicated in the neurobiological pathways of schizophrenia. This meta-analysis evaluated the efficacy and tolerability of adjunctive celecoxib as a noncompetitive anti-inflammation drug in treating schizophrenia. Data were searched, extracted, checked and entered into the RevMan (version 5.3) software by two independent investigators. Standardized/weighted mean differences (SMDs/WMDs), risk ratio (RR) and their 95% confidence intervals (CIs) were calculated, as appropriate. Included were 8 randomized controlled trials (RCTs) with a total of 626 patients with schizophrenia including 316 (50.5%) treated on celecoxib (400 mg/day) and 310 (49.5%) on placebo over 8.3 ± 2.3 weeks of treatment. Adjunctive celecoxib outperformed placebo with respect to total psychopathology [3 RCTs, n = 180; SMD: -0.47; 95%CI: -0.81, -0.14; P = 0.005; I2 = 18%; 'moderate quality'], symptoms positive [3 RCTs, n = 180; SMD: -0.50; 95%CI: -0.79, -0.20; P = 0.001; I2 = 0%; 'moderate quality'], negative symptoms [3 RCTs, n = 180; SMD: -0.32; 95%CI: -0.66, 0.02; P = 0.06; I2 = 22%; 'moderate quality'], and general psychopathology scores [3 RCTs, n = 180; SMD: -0.35; 95%CI: -0.65, -0.06; P = 0.02; I2 = 0%; 'moderate quality'] in first-episode, but not chronic patients. Additionally, superiority of celecoxib for the Positive and Negative Syndrome Scale (PANSS) total scores was moderated by higher PANSS positive scores and lower PANSS negative scores at baseline. All-cause discontinuation [RR: 1.02; (95%CI: 0.56, 1.86); P = 0.94; I2 = 0%] and adverse drug reactions were similar between the two groups. Adjunctive celecoxib appears to be an efficacious and safe treatment in improving psychotic symptoms, particularly in first-episode schizophrenia.

Abstract
Abstract
Introduction The purpose of this study is to systematically review the efficacy and safety of adjunctive erythropoietin (EPO) in treating cognitive deficits associated with schizophrenia, bipolar disorder, and major depression based on randomized controlled trials (RCTs).
Methods Two evaluators independently and systematically searched and selected studies, extracted data, and conducted quality assessment.
Results Four RCTs with 144 patients (71 in the EPO group and 73 in the placebo group) met the study entry criteria. Adjunctive EPO could improve schizophrenia-related cognitive performance. In patients with bipolar disorder, EPO could also enhance sustained attention, recognition of happy faces, and speed of complex information processing across learning, attention, and executive function when compared with placebo. In addition, EPO could enhance verbal recall, recognition, and memory in patients with major depression.
Discussion This preliminary study found that adjunctive EPO appears to be effective in treating cognitive deficits associated with schizophrenia, bipolar disorder, and major depression without major adverse effects observed. Further higher quality RCTs with larger samples are needed to confirm the findings.

Abstract
Background Tardive dyskinesia (TD) is characterized by abnormal and involuntary movements. Importantly, TD could cause considerable personal suffering and social and physical disabilities. Aims This meta-analysis based on randomized controlled trials (RCTs) systematically assessed the therapeutic effect and tolerability of melatonin for TD in schizophrenia. Methods A computerized and systematical search of both Chinese (Wanfang Data, Chinese National Knowledge Infrastructure (CNKI), SINOMED) and English (PubMed, PsycINFO, Embase, Cochrane Library databases) databases, from their inception until June 8, 2017, was conducted by two independent authors. The severity of TD symptoms were the primary outcome measure and analyzed using a random effects model by the Review Manager (RevMan) Version 5.3. Quality evaluation of included RCTs was conducted using the Cochrane risk of bias and Jadad scale. The GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) system recommendation grading method was used to assess the overall quality level of meta-analytic outcomes. Results Four RCTs (n=130) were identified and analyzed. Three RCTs used double blind and 1 RCT used masked assessors using the Cochrane risk of bias, and 3 RCTs were rated as high quality based on Jadad scale. Compared with the control group, adjunctive melatonin was superior in reducing the severity of TD as measured by the Abnormal Involuntary Movement Scale (AIMS) (4 RCTs, n=130, weighted mean difference (WMD): -1.52 (95% confidence intervals (CI): -3.24, 0.20), p=0.08; I2=0%) although the improvement did not reach a significant level. The overall evidence quality of the improvement of TD symptoms, according to GRADE approach, was rated as “Low”. The data on the ADRs and cognitive effect were limited. Conclusions This meta-analysis shows that melatonin has potential for improving TD symptoms in schizophrenia. Future higher quality and larger RCTs are warranted to confirm the findings.

Abstract
Hyperprolactinemia is a common and severe antipsychotic-induced adverse drug reaction. This meta-analysis of randomized controlled trials systematically examined the efficacy and safety of adjunctive metformin for antipsychotic-related hyperprolactinemia in schizophrenia patients. Two independent investigators searched, extracted, and synthesized data. Weighted mean differences and risk ratios with their 95% confidence intervals were calculated using random effect model. Four randomized controlled trials ( n=509) comparing adjunctive metformin ( n=253) with the control groups ( n=256), lasting 22.7 weeks of treatment, were included in the meta-analysis. The metformin group had significantly lower serum prolactin level at endpoint (four randomized controlled trials, n=501; weighted mean difference: -6.87 ug/L (95% confidence interval: -13.24 to -0.51), p=0.03; I2=80%) with "moderate quality" based on the grading of recommendations assessment, development, and evaluation system. In patients with menstrual disturbances, the rate of menstruation resumption was 66.7% in the metformin group and 4.8% in the control group. Adverse drug reactions and all-cause discontinuation (three randomized controlled trials, n=339, risk ratio: 0.76 (95% confidence interval: 0.29, 1.97), p=0.57; I2= 0%) were similar between the two groups. Adjunctive metformin appears to be effective and safe for reducing antipsychotic-induced hyperprolactinemia and prolactin-related symptoms in schizophrenia patients. Higher quality randomized controlled trials with a large sample size are warranted to confirm these findings.

Abstract
This study aimed to conduct a meta-analysis of the efficacy and safety of adjunctive minocycline for schizophrenia. Randomized controlled trials (RCTs) comparing adjunctive minocycline with placebo in patients with schizophrenia were included in the meta-analysis. Two independent investigators extracted and synthesized data. Standard mean differences (SMDs), risk ratio (RR) ±95% confidence intervals (CIs) and the number-needed-to-harm (NNH) were calculated. Eight RCTs with 548 schizophrenia patient including 286 (52.2%) patients on minocycline (171.9±31.2mg/day) and 262 (47.8%) on placebo completed 18.5±13.4 weeks of treatment. Meta-analyses of Positive and Negative Syndrome Scale (PANSS) (7 RCTs with 8 treatment arms)/Brief Psychiatric Rating Scale (BPRS) (1 RCT) total score [SMD: -0.64, (95%CI: -1.02, -0.27), P=0.0008; I2=74%], positive, negative and general symptom scores [SMD: -0.69 to -0.22 (95%CI: -0.98, -0.03), P=0.02-0.00001; I2=7-63%] revealed a significant superiority of adjunctive minocycline treatment over the placebo. There was no significant difference regarding neurocognitive function, discontinuation rate and adverse drug reactions between the two groups. This meta-analysis showed that adjunctive minocycline appears to be efficacious and safe for schizophrenia. Due to significant heterogeneity, future studies with a large sample size are needed to confirm these findings.
