The normalized relative expression levels of UGT2B17 (a) and UTS2 (b) in the peripheral blood samples from Chinese (n = 29) and Caucasian (n = 37) males. Dots represent relative gene expression in the individual samples. The upper and lower edges of the boxes correspond to the first (Q1) and third (Q3) quartiles, respectively. The lines inside the boxes indicate the median expression values. The whiskers extend to the smallest and the largest observations within the 1.5-times interquartile range (IQR) from the box
