Aim: The progress of a discipline depends on the knowledge widely shared, an aim fulfilled by publications. But which are the factors influencing publication? We examine predictors of a subsequent publication for abstracts submitted to the annual scientific conference of the German Society of Orthodontics (DGKFO)., Methods: For all 288 abstracts presented in 2014 and 2015 we recorded presentation format, number and gender of authors, study design and university affiliation. Subsequent publication as a peer-reviewed full-text article was researched over a period of more than three years., Results: A total of 88 abstracts (30.6 %) were published in full-text after a mean time span of 1.2±1.6 years after the respective conference. In multivariate logistic regression, secondary studies (OR 9.27 [1.51-57.04]; p=0.016), a higher number of authors (OR 1.21 [1.02-1.43]; p=0.030), a higher percentage of female authors (OR 1.01 [1.00-1.03]; p=0.036) but male gender of the first author (OR 2.10 [1.11-3.98]; p=0.023) resulted in a higher probability of getting published as a journal paper., Conclusion: Our investigation shows that secondary studies, a higher number of authors, a higher percentage of women among the authors and male first authors are predictive factors of publication. After more than three years, only about one third of the abstracts presented at the DGKFO annual scientific conference have been published as a full-text journal article, meaning that a huge part of knowledge remains unshared., (Copyright © 2021.
