Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Twenty Veterans Affairs Medical Centers (VAMCs) were selected to participate in this cooperative study. The recruitment period was from 12/01/00 to 05/31/03.
