Project description:ObjectiveAbstracts submitted to meetings are subject to less rigorous peer review than full-text manuscripts. This study aimed to explore the publication outcome of abstracts presented at the American Academy of Ophthalmology (AAO) annual meeting.MethodsAbstracts presented at the 2008 AAO meeting were analyzed. Each presented abstract was sought via PubMed to identify if it had been published as a full-text manuscript. The publication outcome, journal impact factor (IF), and time to publication were recorded.ResultsA total of 690 abstracts were reviewed, of which 39.1% were subsequently published. They were published in journals with a median IF of 2.9 (range 0-7.2) and a median publication time of 426 days (range 0-2,133 days). A quarter were published in the journal Ophthalmology, with a shorter time to publication (median 282 vs. 534 days, p=0.003). Oral presentations were more likely to be published than poster presentations (57.8% vs. 35.9%, p<0.001) and in journals with higher IFs (3.2 vs. 2.8, p=0.02). Abstracts describing rare diseases had higher publication rates (49.4% vs. 38.0%, p=0.04) and were published in higher IF journals (3.7 vs. 2.9, p=0.03), within a shorter period of time (358 vs. 428 days, p=0.03). In multivariate analysis, affiliation with an institute located in the United States (p=0.002), abstracts describing rare diseases (p=0.03), and funded studies (p=0.03) were associated with publication in higher IF journals.ConclusionsAlmost 40% of abstracts were published. Factors that correlated with publication in journals with higher IF were a focus on rare diseases, affiliation with a US institute, and funding.
Project description:Background contextAcademic meetings serve as an opportunity to present and discuss novel ideas. Previous studies have identified factors predictive of publication without generating predictive models. Machine learning (ML) presents a novel tool capable of generating these models. As such, the objective of this study was to use ML models to predict subsequent publication of abstracts presented at a major surgical conference.Study design/settingDatabase study.MethodsAll abstracts from the North American Spine Society (NASS) annual general meetings (AGM) from 2013-2015 were reviewed. The following information was extracted: number of authors, institution, location, conference category, subject category, study type, data collection methodology, human subject research, and FDA approval. Abstracts were then searched on the PubMed, Google Scholar, and Scopus databases for publication. ML models were trained to predict whether the abstract would be published or not. Quality of models was determined by using the area under the receiver operator curve (AUC). The top ten most important factors were extracted from the most successful model during testing.ResultsA total of 1119 abstracts were presented, with 553 (49%) abstracts published. During training, the model with the highest AUC and accuracy metrics was the partial least squares (AUC of 0.77±0.05, accuracy of 75.5%±4.7%). During testing, the model with the highest AUC and accuracy was the random forest (AUC of 0.69, accuracy of 67%). The top ten features for the random forest model were (descending order): number of authors, year, conference category, subject category, human subjects research, continent, and data collection methodology.ConclusionsThis was the first study attempting to use ML to predict the publication of complete articles after abstract presentation at a major academic conference. Future studies should incorporate deep learning frameworks, cognitive/results-based variables and aim to apply this methodology to larger conferences across other fields of medicine to improve the quality of works presented.
Project description:BackgroundPresentations at scientific conferences are an important method of research dissemination, with abstracts often used to inform clinical practice. Abstract to publication ratio is a commonly used tool for determining meeting quality. The aim of this study was to determine the publication rate for abstracts presented at the Australian Orthopaedic Association Annual Scientific Meeting (AOA ASM) between 2012 and 2015 inclusive and identify reasons for non-publication.MethodsMEDLINE, PubMed and Google Scholar were searched to determine whether each abstract presented at AOA ASMs between 2012 and 2015 was associated with a full text publication in a peer-reviewed journal. Where a publication could not be located, the presenter was contacted to confirm the reason for non-publication.ResultsA total of 1130 abstracts were submitted (951 oral and 179 posters), and 573 resulted in full-text peer-reviewed publications (51%). The majority of publications (73%) were published within 2 years of presentation. There was no difference in likelihood of publication for oral presentations compared to posters, nor in the rate of publication across the 4 years of meetings. Common reasons for non-publication were lack of time (32%), publication considered low priority (27%) and journal rejections (22%).ConclusionThe overall publication rate for abstracts presented at the AOA ASM is 51%, which is an increase from the 1998 ASM (31%). This publication rate is higher than many similar Australian meetings and on par with other international orthopaedic and subspecialty meetings. Future research should investigate potential publication bias and methods to minimise barriers to publication.
Project description:Peruvian research output is one of the lowest in South America and is limited to the work of a small group of institutions and related to few subjects, such as infectious diseases. We determined the proportion of subsequent publication and its associated factors of the abstracts with Peruvian affiliation presented to the American Society of Tropical Medicine and Hygiene annual meetings between 2006 and 2010. Approximately 27% (79/296) of abstracts were published within 6 years of presentation, with a median time to publication of 16 months (interquartile range: 9-28). In the adjusted analysis, abstracts with a higher proportion of authors from Peruvian institutions were less likely to be published (risk ratio: 0.5; 95% CI: 0.3-0.8). In conclusion, one of four of the analyzed abstracts was published. Even though this proportion is higher than that in other meetings in Peru and South America, publication rates -especially among Peruvian-only collaborations- still need to be improved.
