The publication fate of abstracts awarded prizes at European Society of Paediatric Radiology annual scientific meetings

Background The European Society of Paediatric Radiology (ESPR) awards prizes for outstanding work presented at their annual scientific meetings. The proportion of ESPR prize-winning abstracts to journal publications is not known. Contextualising abstract-to-publication proportions by evaluating publication experience can yield valuable insights and actionable outcomes to support researchers in overcoming barriers to journal publication.

Objective To assess the abstract-to-publication proportion of prize-winning ESPR abstracts and prize-winning authors’ experience of publishing in Pediatric Radiology, the affiliated journal of the ESPR and other specialist international paediatric radiology societies.

Materials and methods PubMed was searched for titles of ESPR prize-winning abstracts from 1977 (the year of first award) up to and including 2021, where the presenter was either first or co-author, and the article was published 2 years before or after the presentation year. If not found, a general internet search was performed. Titles of all retrieved articles were evaluated for inclusion. A survey was distributed to all ESPR prize winners to better understand their experiences around journal submission.

Results Over 44 years, 108 prizes were awarded. The prize-winning abstract-to-publication proportion was significantly higher (59.3%, OR=2.10, P=0.012) than the recently published pediatric radiology “abstract to publication rate” (41.9% from 2013–2016). Moreover, prize winners were more than twice as likely than to achieve journal publication (OR=2.10), and as first author (OR=1.33). The majority of awardees published their work as first author (52/64, 81.3%): the first-author abstract-to-publication proportion was not significantly higher than the paediatric radiology “abstract-to-publication rate” (48.1%, OR=0.33, P=0.330). Sixty-four survey responses were received (59.3%, out of a total 108 awarded prizes). Just over 20% of prize-winning work was published in Pediatric Radiology, with 41.5% of respondents reporting a good to excellent submission experience.

Conclusion Prize-winning and first-author abstract-to-publication proportions are higher for ESPR-awarded abstracts than the most recently reported paediatric radiology “abstract-to-publication rate”, suggesting that prizes are either awarded to work most likely to be published or that being awarded a prize encourages publication. Given that just over 40% of prize-winning abstracts remain unpublished, the ESPR should do more to support and encourage all authors to publish their work.
