Methods: This was a retrospective cohort study set in a network of VA facilities that includes Southern California and Nevada, with an enrollment of 1.4 million veterans. Socioeconomic status was estimated using zip code median household income. Differences in medication possession ratio (MPR) associated with copayment was the primary outcome measure.
