Selection steps of study participants from the HIV Outpatient Study, USA, 2007–2021. ^∗LDL-C tests within a window of 6 months prior to ART initiation date and 30 days following the initiation were assessed. For the participants with multiple tests, the LDL-C value closest to the initiation date was used. ^∗∗non-HDL-C was calculated as the total cholesterol result minus the HDL result. Total cholesterol and HDL results had to have been collected on the same day. Abbreviations: ART, antiretroviral therapy; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; NRTI, nucleoside reverse transcriptase inhibitor.
