Abstract
INTRODUCTION the presentation of research at a congress is an interesting means for scientific dissemination, but only with publication in an indexed journal does the data become accessible and disseminated. The conversion rate in published articles of abstracts presented at congresses is an indicator to assess the scientific quality of those events. The aim of this study is to evaluate bibliometric characteristics of abstracts presented at the Brazilian Congress of Coloproctology and to determine the factors that affect publication rates. METHODS Retrospective evaluation of all abstracts presented at the Brazilian Congresses of Coloproctology from 2015 to 2019. Multiple databases were analyzed to estimate the conversion rate of the presented papers, as well as variables associated with the conversion of abstracts into full manuscripts through bivariate analysis and multivariate variables of these predictors. RESULTS 1756 abstracts were analyzed. Most studies are retrospective, series or case reports, and even personal experience. The conversion rate was 6.9%. The presence of statistical analysis was twice as high for published abstracts as for unpublished ones. CONCLUSION the data presented demonstrate a low scientific productivity of the specialty, since the research carried out is, for the most part, not published as complete manuscripts. The predictors of publication of abstracts were: multicenter studies, studies with statistical analysis, study designs with a higher level of evidence and studies awarded by the congress.

Nascimento S, Rahal RMS, Soares LR, de Souza Pimentel HJ, Kamimura TO, Freitas-Junior R. Publication rate of scientific papers presented at the largest event on breast cancer research in Latin America. Ecancermedicalscience 2021; 15:1259. [PMID: 34567244 PMCID: PMC8426010 DOI: 10.3332/ecancer.2021.1259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2021] [Indexed: 11/25/2022] Open
Abstract
Purpose Medical congresses allow scientific production to be appropriately disseminated and discussed. However, most of the scientific papers presented at medical congresses do not go on to be published in indexed journals. The present study aimed to determine the publication rate of papers presented at the Brazilian Breast Cancer Symposium (BBCS) and trends associated with publication over that timeframe. Methods This was a retrospective, observational study evaluating scientific papers presented at the BBCS between 2012 and 2017. All the abstracts presented at the event within this timeframe were recorded. Next, a search for papers was made using online databases (BIREME/LILACS and MEDLINE/PubMed) and in the curricula of the authors on the Lattes Platform. Results Overall, 543 abstracts of papers presented at the BBCS between 2012 and 2017 were included. Of these, 112 (20.6%) had been published in an indexed journal, mostly in English (67.0%), in journals with an impact factor of 2.0–3.0 (21.4%) and ≥1 year after presentation at the event (75.9%). The factors associated with publication were: study conducted in a public institution (p = 0.01), oral or commented poster presentation (p > 0.001) and study concerning rehabilitation following breast cancer (p = 0.04). There was a downward trend in the rate of publication of articles over the years (p = 0.01). Conversely, the impact factor of the publications increased significantly between 2012 and 2017 (p = 0.04). Conclusion The publication rate of papers presented at the BBCS is low and remains consistent over the study period despite academic incentives and substantial awards.

Discrepancies between Conference Abstracts and Published Manuscripts in Plastic Surgery Studies: A Retrospective Review. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2021; 9:e3828. [PMID: 34549011 PMCID: PMC8448048 DOI: 10.1097/gox.0000000000003828] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Accepted: 07/22/2021] [Indexed: 11/26/2022]
Abstract
Background Inconsistency in results and outcomes between presented abstracts and corresponding published articles can negatively affect clinical education and care. The objective of this study was to describe the frequency of clinically meaningful change in results and outcomes between abstracts presented at the American Association of Plastic Surgeons annual conference and the corresponding published articles, and to determine risk factors associated with discrepancies. Methods All abstracts delivered as oral presentations at the American Association of Plastic Surgeons conference (2006-2016) were reviewed. Results and outcomes were compared with those in corresponding articles. We defined clinically meaningful discrepancy as any change in the directionality of an outcome, or a quantitative change in results exceeding 10%. Results Four hundred eighty-six abstracts were identified. Of these, 63% (N = 305) advanced to publication. Of the published studies, 19% (N = 59) contained a discrepancy. In 85% of these (N = 50), discrepancies could not be explained by random variation. Changes in sample size were associated with heightened risk for a discrepancy (OR 10.38, 95% CI 5.16-20.86, P < 0.001). A decrease in sample size greater than 10% increased the likelihood of a discrepancy by 25-fold (OR 24.92, 95% CI 8.66-71.68, P < 0.001), whereas an increase in sample size greater than 10% increased the likelihood of a discrepancy by eight-fold (OR 8.36, CI 3.69-19.00, P < 0.001). Conclusions Most discrepancies between abstract and published article were not due to random statistical variation. To mitigate the possible impact of unreliable abstracts, we recommend abstracts be marked as preliminary, that authors indicate whether sample size is final at time of presentation, and that changes to previously reported results be indicated in final publications.

Abstract
PURPOSE The current study aimed to determine the publication outcome of abstracts presented at the 16th European Congress of Endocrinology (ECE 2014). METHODS All presentations were collected with the web scraping - Python coding from the official website and converted into Google Scholar and PubMed search links with coding. A particular interface was coded to evaluate the results. An online survey was sent to the authors to assess the impact of congress on their publication. RESULTS A total of 1205 abstracts from 71 countries were featured at the congress of which, 1145 (95%) were poster presentations (PP), and 60 (5%) were oral presentations. Subsequently, 341 abstracts (28.3%) were published as a full paper. There was no major change from the abstract in 73.3% of full articles whereas 68.9% had at least one minor change. OP had higher conversion rates to publication than PP (65% vs 26.4; p = 0.01) and a higher median number of citations than PP (12 vs 6; p = 0.01). The median time to publication was 12 months (IQR: 2-24 months). OP was published in journals with a higher median impact factor (IF) than PP (5 vs 2.94; p = 0.01). Multi-country collaborative studies turned into more publications than single-country studies (OR: 3.91 95% CI: 2.52-6.06; p < 0.01). The congress's potential IF was calculated as 3.18. Among the authors responded to survey, 95% indicated that presenting at the congress was valuable for preparation of their publication. CONCLUSIONS This first study evaluating the publication outcome of an international endocrinology congress suggests a 28.3% publication ratio with low discrepancy and 3.18 IF for ECE 2014.

Abstract
BACKGROUND The American Society for Reconstructive Microsurgery (ASRM) annual meeting is a forum to present new research abstracts prior to peer-reviewed publication. The aim of this study is to determine the conversion rate, discrepancies, and time between presentation and publication. METHODS A comprehensive literature search was conducted cross-referencing ASRM abstracts presented between 2014 and 2018 with peer-reviewed manuscripts. The title and authors of the abstract and manuscript, the journal of manuscript publication, and time in months between presentation and publication were recorded. The conversion rate was calculated as the proportion of publications to abstracts. Major discrepancies were defined as changes in the purpose, study design, methods, sample size, statistical analysis, results, or conclusions. Minor discrepancies were defined as changes in the title or authorship. RESULTS Out of 667 oral abstract presentations, 361 (54%) resulted in publication. Of these abstracts, 53 were presented after their corresponding manuscripts were published. The mean conversion rate was 55.52 ± 10.17%. The mean time from presentation to publication was 13.83 months. Minor discrepancies were more frequent than major discrepancies (91 vs. 76%). The most common major and minor discrepancies involved changes in the results (63%) and authorship (79%), respectively. There was a significant association between the year of abstract presentation and whether the conclusion was changed (p = 0.001), but interyear relationships with all other discrepancies failed to reach statistical significance. CONCLUSION Only around half of abstracts presented at the annual ASRM conference have reached full publication in peer-reviewed journals, and most are undergoing significant changes between presentation and publication. This may be due to panel discussions at meetings suggesting study modifications, as well as revisions after careful peer review. Altering surgical practices may not be recommended based on abstracts' content.

Abstracts presented at the European Association for Osseointegration (EAO) Congresses: Publication fate and discrepancies with full-length articles. Clin Oral Implants Res 2020; 31:715-726. [PMID: 32460381 DOI: 10.1111/clr.13620] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2019] [Accepted: 04/29/2020] [Indexed: 11/27/2022]
Abstract
OBJECTIVES To investigate the full publication proportion (FPP) of abstracts presented at the 2010 and 2011 EAO Congresses, analyse the discrepancies between abstracts and their full publications, and explore potential predictors of FPP and discrepancies. METHODS Abstracts presented at the 2010 and 2011 EAO Congresses were retrieved. Associated full publications were identified by searching PubMed, Embase and Google Scholar. Discrepancies between abstracts and full publications were identified, classified and evaluated using a discrepancy score. The Kaplan-Meier survival analysis was used to describe cumulative FPP over time. Predictors for FPP and the discrepancy score were analysed using cox regression modelling and a linear regression model, respectively. RESULTS 850 abstracts were included. The overall FPP was 36.4% with a median time lapse of 12 months. Higher FPP were significantly associated with oral presentation (HR=2.33; 95% CI: 1.68 to 3.22; p<0.001), multiple affiliations (HR =1.32; 95% CI: 1.00 to 1.73; p=0.048) and presence of statistical tests (HR =1.78; 95% CI: 1.36 to 2.32; p<0.001). 91.3% pairs had at least one minor change from the abstract and 70.9% had at least one major change. Greater discrepancy score was significantly associated with longer time lapse (B=0.06; 95% CI: 0.04 to 0.08; p<0.001) and being clinical research (B=1.30; 95% CI: 0.52 to 2.08; p=0.001). CONCLUSIONS Thirty-six percent of abstracts presented at the EAO Congresses were published. Among these, more than two-thirds showed at least one major change in their full publications. Abstracts presented in oral implantology conferences should not be relied upon to inform practice.
