Publication outcome of research presented at the European Congress of Endocrinology: a web scraping-based analysis and critical appraisal.

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.
