Delays in third-line antiretroviral treatment initiation

For this study, the overall delay was defined as the time from the first detected viral load (≥ 1000 copies/mL) after completing at least a year on second-line ART to the date the patient received TLART. The overall delay was stratified by hospital, age category and gender. The rank-sum test and the K-test for equality of medians were used to explore differences in total delay for the different strata.
