p<0.01, paired t test between the basal and induced states.
p<0.05, Wilcoxon rank-sum test for the NR1I2 groups within each CYP2B6 genotype group.
p<0.05, Wilcoxon rank-sum test for the CYP2B6 groups with TGT noncarriers.
p<0.05, Wilcoxon rank-sum test for the CYP2B6 groups with TGT carriers.
Wilcoxon rank-sum test for the CYP2B6 groups; p<0.05 is indicated in bold.
% difference represents the percent difference between basal and induced state, calculated as an absolute of 100×(induced-basal)/basal.
