Linear regression analysis involved numbers of participants shown, for baseline plasma total bilirubin concentration. Analysis among all participants controlled for CYP2B6/CYP2A6 genotype level, age, and sex. Analysis among white, black, and Hispanic participants controlled for the same covariates but did not control for principal components. The two lowest P-value results are shown for each population group.
