AIDS acquired immune deficiency syndrome, HAART highly active antiretroviral treatment, HIV human immunodeficiency virus, NNRTI nonnucleoside reverse transcriptase inhibitor, PI protease inhibitor.
Pooled logistic regression models weighted for the first change in HAART regimen class (weights at the 1st and 99th percentile were truncated) and adjusted for CD4 cell and HIV viral load at initiation, race and ethnicity, HIV transmission risk group, sex, cohort, clinical AIDS diagnosis prior to HAART initiation, year of HAART initiation and month from HAART initiation.
