Figure 2. Relationships between CYP2B6/CYP2A6 genotype levels and day 21 log10 etonogestrel and ethinyl estradiol concentrations among the 24 efavirenz group participants.

Figure 2.

Panel A: associations of CYP2B6/CYP2A6 genotype stratified into 3 levels and log10 ethinyl estradiol concentrations at day 21; Panel B: associations of CYP2B6/CYP2A6 genotype stratified into 3 levels and log10 etonogestrel concentrations at day 21. Error bars indicate median and interquartile range. Linear regression model P-values are shown. ENG = etonogestrel; EE = ethinyl estradiol; EFV = efavirenz. Data from 25 individuals not receiving antiretriviral therapy (ART) are included to the left.
