Fate of Abstracts Presented at the Transplantation Society of Australia and New Zealand Annual Scientific Meetings

Abstract Background The numbers and characteristics of the abstracts presented at the Annual Scientific Meetings (ASM) of the Transplantation Society of Australia and New Zealand (TSANZ) that are converted to peer-reviewed publications have not been analyzed previously. Methods All abstracts presented at the TSANZ ASM from 2013 to 2017 were reviewed. A literature search was performed using a search algorithm to identify the full-text publications of the presented abstracts. Correlation between abstract characteristics and publication rate was then examined using Cox proportional hazards regression and Kaplan-Meier curves to distinguish the predictors for publication. Over the 5-year period, 576 abstracts were presented, with a total of 164 (28.6%) presentations converted to publications. The majority of publications occurred within the first 3 years, with the mean time to publication being 16.6 (standard deviation = 14.6) months. The median impact factor for published research was 4.74 (interquartile range = 3.06-5.58). Multivariate analysis identified clinical science papers, systematic reviews and surveys (likelihood ratio = 1.42, 5.02, and 2.01; P = .040, .000, and .010, respectively) as the most important predictors for publication. Conclusions The rate of abstracts presented at the TSANZ ASM over 5 years that were converted to publication in a peer-reviewed journal was 28.6%. Clinical papers, systematic reviews, and surveys were more likely to be published. An ongoing strict abstract selection process will contribute to improving conversion of abstracts into full-text peer-reviewed articles.
