  1. Note: 1: d4T + 3TC + NVP, 2: d4T + 3TC + EFV, 3: AZT + 3TC + NVP, 4: AZT + 3TC + EFV, 5: TDF + 3TC + EFV, and 6: TDF + 3TC + NVP. The j th entries are the frequencies (percentage) of transition from state to state j. Those in column "no event" are the numbers of patients ending the study in each state and those in column "total entering" are the numbers of patients observed to be in each state at some time point prior to the end of the study
