Adherence, pharmacokinetic, and genetic information.

√Average percentile values were used when multiple drug measurements were performed in a single patient. Drug levels available in 30% of participants on EFV and 50% of those on LPV/r treatment. †EFV: Genetic results available in 86% of patients for the allele CYP2B6*6; No study participants carried a loss/diminished-function CYP2B6*11 or *15 alleles; LPV: Genetic results available in 93% of patients. IQR = interquartile range, Het = heterozygous, Hom = homozygous, LOF = loss of function, Ref = reference allele. NA = not applicable.
