Modeled (95% confidence interval [CI]) reduction in the risk of a severe non-AIDS event or death as a result of an increase in antiretroviral therapy (ART) adherence (ie, intervention) based on a Cox proportional hazard model by Grund et al [20]. A, Risk reduction based on data from the Multicenter AIDS Cohort Study that used self-reported adherence. B, Risk reduction based on data from observational cohorts in Africa and interventional clinical trials that used self-reported adherence and electronic adherence monitoring. Solid black lines represent predicted risk reductions (eg, 10%, 20%). Filled squares represent the estimate, and the colored lines represent the 95% CI for each estimate. Open squares represent the 95% CI upper and lower limits of the estimated risk reduction with their corresponding 95% CI. Uganda Aids Rural Treatment Outcomes (UARTO) 10% and UARTO 20% increase represent a 10% and 20% increase in ART adherence, respectively. Adapted from Grund et al [20].
