  1. aEstimates are standardized to the distribution of sex, race, AIDS diagnosis, prior ART mono- or dual-therapy, age, CD4 cell count and log10 HIV viral load in the total sample at clinic enrollment using inverse probability of exposure weights
  2. bThe RMST spent not on ART but Alive and Retained in Clinic refers to the difference of the integration of the 1-CIF for ART initiation minus the CIF for the composite of mortality and loss-to-clinic
  3. cBased on integration between 1-CIF for ART 2.5th and 97.5th percentiles of 10,000 non-parametric bootstrap resamples
