(a) Cumulative incidence (competing risks analysis) of disengagement, transfer (including silent transfers), and mortality, as estimated by a flexible parametric survival model based on time contributed during a 2-year period, but analyzed relative to ART initiation date, allowing for delayed entry into the analysis. (b) Hazard of disengagement by duration since ART start, with calendar year (2013 versus 2014) fitted as a time-varying covariate in a Cox proportional hazards model. (c) Hazard of disengagement by duration since ART start, with calendar year (2013 versus 2014) fitted as a time-varying covariate in a Cox proportional hazards model adjusted for the patient characteristics listed in Table 2. ART, antiretroviral therapy.
