  1. aSub-distribution hazard ratio model is used considering death as a competing risk of event in the analysis for cumulative retention. However, at 12 months no competing risk was reported
  2. bThe model was adjusted for age, sex, marital status, education, baseline cd4 count, facility type (by shared frailty model); LTFU: Loss to follow-up
