Methods	Identification of subsequent full‐length publications Searched electronic database Embase, MEDLINE, Google/Google Scholar, and Eric to November 2012 Person completing the search not reported Searched by first, second, and last author, keywords, and title Matching criteria not reported
Data	Included 449 abstracts presented at the 2005 to 2006 Research in Medical Education Conference and Canadian Conference on Medical Education meetings Included all abstracts excluding 7 (4 withdrawn, 1 missing, 2 published before abstract deadline)
Comparisons	Proportion of abstracts published, overall and by meeting Median time to publication Cumulative proportion of abstracts published Oral versus poster presentation Multi‐centered versus single center Mixed methods versus qualitative methods versus quantitative methods Multi‐center authorship versus not Research scholarship versus evaluation of program or innovation scholarship versus other scholarly activities Completed works versus work in progress
Outcomes	156 of 449 abstracts published 86/232 abstracts presented at the Research in Medical Education Conference meetings, and 70/217 at the Canadian Conference on Medical Education meetings published Proportion of abstracts published by time Median time to publication = 20 months (IQR = 10 to 30 months, range = ‐9 to 76 months) Cumulative proportion of abstracts published at 60 months showed proportion published = 33.6% (151/449 abstracts) Factors related to proportion of abstracts published included 80/165 abstracts presented orally versus 76/284 abstracts presented as poster published 33/81 abstracts with multiple centers versus 110/301 abstracts with a single center published 20/36 methods with mixed methods design versus 32/69 abstracts with qualitative design versus 91/254 abstracts with quantitative design published 60/118 abstracts with multi‐center authorship versus 96/331 abstracts without multi‐center authorship published 110/283 abstracts on research versus 33/99 abstracts on evaluation of program or innovation versus 16/67 abstracts on other scholarly activity published 125/300 abstracts of completed works versus 18/82 abstracts with works in progress published
