HAART: highly active antiretroviral therapy, ART: antiretroviral therapy.
HAART: current standard HAART regimens (two or more nucleoside reverse transcriptase inhibitors (NRTIs) with a protease inhibitor or a nonnucleoside reverse transcriptase inhibitor (NNRTI) or integrase strand transfer inhibitors (raltegravir) or salvage regimen.
Old HAART: triple combination antiretroviral regimens containing indinavir, saquinavir, fosamprenavir, nelfinavir, or nevirapine.
Any ART: not classified as HAART or old HAART.
Others: ART regimen except HAART (“old HAART” and “any ART”) and “no ART”.
P values are approximations and ages are extrapolations from the regression equation.
