Analytic samples available for inclusion in analyses of PROUD intervention effects before and after randomization. Boxes not drawn to scale. * Increase in documentation of an OUD diagnosis may be due to increased skill in diagnosing and treating OUD or increased patient disclosure due to reduced stigma. ** Includes patients who are attracted to the intervention site because they are seeking OUD treatment (e.g. due to limited access to treatment elsewhere or lower barriers to receiving care in the PROUD intervention site)
