Evaluation of Reporting Quality of Glaucoma Randomized Controlled Trial Abstracts: Current Status and Future Perspectives

The aim of this study was to explore adherence to the Consolidated Standards of Reporting Trials (CONSORT) reporting standards in abstracts of randomized controlled trials on glaucoma. A cross-sectional observational study was conducted on the aforementioned abstracts, indexed in MEDLINE/PubMed between the years 2017 and 2021. In total, 302 abstracts met the inclusion criteria and were further analyzed. The median score of CONSORT-A items was 8 (interquartile range, 7-10) out of 17 (47.0%). Most analyzed studies were conducted in a single center (80.5%) and the abstracts were predominantly structured (95.0%). Only 20.5% of the abstracts adequately described the trial design, while randomization and funding were described by 6.0% of the abstracts. Higher overall scores were associated with structured abstracts, a multicenter setting, statistically significant results, funding by industry, a higher number of participants, and having been published in journals with impact factors above four (p < 0.001, respectively). The results of this study indicate a suboptimal adherence to CONSORT-A reporting standards, especially in particular items such as randomization and funding. Since these factors could contribute to the overall quality of the trials and further translation of trial results into clinical practice, an improvement in glaucoma research reporting transparency is needed.

Quality of Reporting Randomized Controlled Trials Published in Three of the Most Citable Periodontal Journals from 2018 to 2022

This study aimed to evaluate the reporting quality of randomized clinical trials (RCTs) in periodontology. Three leading periodontology journals, the Journal of Periodontology (JOP), the Journal of Clinical Periodontology (JOCP), and the Journal of Periodontal Research (JOPR), were selected for this investigation. The RCTs were identified by manually searching for human trial articles published in these three journals. Two authors independently conducted the literature search, and a pre-piloted extraction sheet was used to screen the potential RCTs. The CONSORT checklist guidelines were employed to calculate the score value. Intra-examiner reliability was assessed by scoring a random sample of 10% of the papers in a second round conducted by the first examiner three months after the initial data collection. A search of abstracts published over a five-year period yielded 176 articles that reported RCTs, accounting for 11.7% of all articles published in the three journals. The highest number of RCTs was published in 2020, and more than half of the included RCTs (51%) originated from Europe. Many of the analyzed RCTs inadequately reported almost half of the items on the CONSORT checklist. Furthermore, univariate analysis revealed significant associations between certain factors and the overall CONSORT score, such as publication in JOP (p = 0.048), publication year of 2019 (p = 0.041) and 2021 (p = 0.042), first author from North America (p = 0.016), and RCTs with more than six authors (p = 0.042). Clinical trial research in periodontics has made significant progress in the past five years. However, there is room for improvement in adhering to the CONSORT guidelines.

Current status of the reporting quality of abstracts in systematic reviews related to implant dentistry: a literature survey

The aim of this study was to assess the reporting quality of abstracts in systematic reviews (SRs) related to implant dentistry and to assess the possible factors associated with the reporting quality. Abstracts of SRs in the field of implant dentistry, published in the last 5 years, were searched. The reporting quality was assessed and scored using the PRISMA for Abstracts checklist (PRISMA-A). The overall PRISMA-A score (OPS) and relative score (OPS%) per review were calculated according to adherence to the criteria presented in the checklist. Multivariable linear regression was performed to identify possible factors associated with reporting quality. Overall, 310 SRs were eligible for this study. Based on the maximum PRISMA-A score (score of 12), the mean OPS was 6.5 and OPS% was 54.2%. The items 'title', 'objectives', and 'number of included studies' were those most frequently reported in the abstracts, while the items 'registration' and 'funding' were the least reported. According to multivariable linear regression, the geographical origin of the articles was the only factor associated with better quality of abstract reporting, with higher OPS for SRs from Europe when compared to North America (coefficient 0.73; P = 0.049). The reporting quality of abstracts in SRs related to implant dentistry is suboptimal and needs to be improved. Journals should encourage adherence to reporting checklists in SRs.

Did an introduction of CONSORT for abstracts guidelines improve reporting quality of randomised controlled trials' abstracts on Helicobacter pylori infection? Observational study

OBJECTIVE

To determine abstracts' adherence to the Consolidated Standards of Reporting Trials for Abstracts (CONSORT-A) statement and to explore the factors associated with reporting quality.

DESIGN

An observational study.

SETTING

Abstracts of randomised controlled trials published between 2010 and 2019, found searching the MEDLINE database.

PARTICIPANTS

A total of 451 abstracts of the clinical trials on Helicobacter pylori infections were included.

PRIMARY AND SECONDARY OUTCOME MEASURES

Abstracts' reporting quality was determined by assessing their adherence to 17-item CONSORT-A checklist, with overall score being calculated as the sum of items that were adequately reported for each abstract. Additional factors that might influence the reporting quality of the abstracts were analysed, with univariate and multivariate linear regression used to determine how those factors influenced the overall reporting quality.

RESULTS

Included abstracts had an overall median quality score of 8/17 (IQR 7-9). Large proportions of abstracts adequately reported interventions, participants, objectives, numbers randomised and conclusions (97.1, 99.3, 89.1. 94.7 and 98.4% of abstracts, respectively). Trial design, randomisation, blinding and funding were severely under-reported with only 8.0, 2.7, 11.0 and 2.0% of abstracts reporting each item. Overall quality scores for H. pylori abstracts were higher in association with CONSORT-A endorsement (B=5.698; 95% CI 1.781 to 9.615), pharmacological interventions (B=4.063; 95% CI 0.224 to 7.902), multicentre settings (B=5.057; 95% CI 2.370 to 7.743), higher numbers of participants (B=3.607; 95% CI 1.272 to 5.942), hospital settings (B=4.827; 95% CI 1.753 to 7.901) and longer abstracts (B=3.878; 95% CI 0.787 to 6.969 for abstracts with 251-300 words and B=7.404; 95% CI 3.930 to 10.878 for abstracts with more than 300 words).

CONCLUSIONS

The overall reporting quality of abstracts was inadequate. The endorsement of CONSORT-A guidelines by more journals might improve the standards of reporting.

Evaluation of reporting quality of abstracts of randomized controlled trials regarding patients with COVID-19 using the CONSORT statement for abstracts

OBJECTIVE

To evaluate the reporting quality of randomized controlled trial (RCT) abstracts regarding patients with coronavirus disease 2019 (COVID-19) and to analyze the factors influencing the quality.

METHODS

The PubMed, Embase, Web of Science, and Cochrane Library databases were searched to collect RCTs on patients with COVID-19. The retrieval time was from inception to December 1, 2020. The CONSORT statement for abstracts was used to evaluate the reporting quality of RCT abstracts.

RESULTS

A total of 53 RCT abstracts were included. The CONSORT statement for abstracts showed that the average reporting rate of all items was 50.2%. The items with a lower reporting quality were mainly the trial design and the details of randomization and blinding (<10%). The mean overall adherence score across all studies was 8.68 ± 2.69 (range 4-13.5). Multivariate linear regression analysis showed that the higher reporting scores were associated with higher journal impact factor (P < 0.01), international collaboration (P = 0.04), and structured abstract format (P < 0.01).

CONCLUSIONS

Although many RCTs on patients with COVID-19 have been published in different journals, the overall quality of reporting in the included RCT abstracts was suboptimal, thus diminishing their potential usefulness, and this may mislead clinical decision-making. In order to improve the reporting quality, it is necessary to promote and actively apply the CONSORT statement for abstracts.

Assessment of reporting quality in randomised controlled clinical trial abstracts of dental implantology published from 2014 to 2016

OBJECTIVES

Access to full texts of randomised controlled clinical trials (RCTs) is often limited, so brief summaries of studies play a pivotal role. In 2008, a checklist was provided to ensure the transparency and completeness of abstracts. The aim of this investigation was to estimate adherence to the reporting guidelines of the Consolidated Standards of Reporting Trials (CONSORT) criteria for abstracts (CONSORT-A) in RCT publications.

PRIMARY ENDPOINT

Assessment according to the percentage of compliance with the 16 CONSORT-A criteria per study.

MATERIALS AND METHODS

This study is based on a full survey (212 RCT abstracts in dental implantology, PubMed search, publication period 2014-2016, 45 journals, median impact factor: 2.328). In addition to merely documenting 'adherence' to criteria, the authors also assessed the 'complete implementation' of the requested information where possible. The collection of data was performed independently by two dentists, and a final consensus was reached. The primary endpoint was evaluated by medians and quartiles. Additionally, a Poisson regression was conducted to detect influencing factors.

RESULTS

A median of 50% (Q1-Q3: 44%-63%) was documented for the 16 criteria listed in the CONSORT-A statement. Nine of the 16 criteria were considered in fewer than 50% of the abstracts. 'Correct implementation' was achieved for a median of 43% (Q1-Q3: 31%-50%) of the criteria. An additional application of Poisson regression revealed that the number of words used had a locally significant impact on the number of reported CONSORT criteria for abstracts (incidence rate ratio 1.001, 95% CI 1.001 to 1.002).

CONCLUSION

Transparent and complete reporting in abstracts appears problematic. A limited word count seems to result in a reduction in necessary information. As current scientific knowledge is often not readily available in the form of publications, abstracts constitute the primary basis for decision making in clinical practice and research. This is why journals should refrain from limiting the number of words too strictly in order to facilitate comprehensive reporting in abstracts.
