      • Methodology

      • Hypothesis
Data

Comparisons

  • Proportion of abstracts published

  • Mean and median time to publication, overall and by type of research

  • Cumulative proportion of abstracts published

  • Oral versus poster presentation

  • Clinical versus basic science research

  • Presentation in plenary session versus presentation in another format

    • Median time to publication = 17 months (IQR = 9 to 28 months) for abstracts describing clinical research

    • Median time to publication = 13 months (IQR = 5 to 26 months) for abstracts describing basic science research)

    • Cumulative proportion of abstracts published at 60 months showed proportion published = 59.1% (1269/2149 abstracts)

  • Factors related to proportion of abstracts published included

    • 259/378 abstracts presented orally versus 1012/1772 abstracts presented as poster published
