| History of AIDS, n (%) | 123 (12) | 189 (24) | 312 (17) |
Differences between low and high HIV RNA stratum: P < .05 for sex, race/ethnicity, age, CD4+ cell count, calculated creatinine clearance, and history of AIDS. Number missing baseline race or ethnicity category 5, and CD4+ cell count 1.
Abbreviation: HIV indicates human immunodeficiency virus.
a
Race or ethnicity group was self reported.
b
Baseline RNA is calculated as mean of pre-entry and entry log10 (copies/mL). Baseline CD4+ count is calculated as the mean of pre-entry and entry values.
