Methods	Identification of subsequent full‐length publications Searched electronic database PubMed until June 2010 Person completing the search not reported Searched by first and last author, and title Matching criteria not reported
Data	Included 73 abstracts submitted to the 2005 American Society of Nephrology meeting Included all abstracts of completed randomized controlled trials
Comparisons	Proportion of abstracts published Median time to publication Industry funding Oral versus poster presentation Multi‐centered Statistically significant results European versus North American origin Asian versus North American origin
Outcomes	39 of 73 abstracts published Proportion of abstracts published by time Median time to publication = 24 months (IQR = 13 to 36 months) Factors related to proportion of abstracts published included Industry funding = OR 2.92 (95% CI = 1.09 to 7.85) Oral versus poster presentation = OR 3.66 (95% CI = 1.29 to 10.39) Multi‐centered versus single center = OR 1.71 (95% CI = 0.59 to 5.02) Positive results (defined as statistically significant) results versus not positive = OR 1.59 (95% CI = 0.57 to 4.49) European versus North American origin = OR 0.61 (95% CI = 0.19 to 1.89) Asian versus North American origin = OR 0.18 (95% CI = 0.05 to 0.72)
Notes	Nephrology Funding not reported
