Data for HIV-positive subjects came from study PROA1004. Data for HIV-negative subjects are pooled data from studies PROA1010 and PROA1011. Bilirubin concentration was measured in milligrams per deciliter, weight was measured in kilograms, and age was measured in years. For race, “black” was assigned a value of 1 and “white” and “other” were assigned a value of 0.
