Data	Included 655 abstracts presented at the 2003, 2005, and 2007 Great Lakes Pharmacy Residency Conference meetings Included all abstracts
Comparisons	Proportion of abstracts published, overall and by meeting Mean time to publication Clinical research versus basic science research versus survey versus service development RCT design versus observational design versus other interventional design Academic center versus veterans affairs institution versus community/retail institution versus hospital versus other institution affiliation Prospective versus retrospective design Results presented in abstract versus not Intervention on drugs versus humans versus other topics
