While the decreases observed in the different CYP2C19 metabolizing groups were not significant ( p trend = 0.26), the difference approached significance ( p = 0.089) when comparing the combined UM 2C19 + EM 2C19 groups (11.9 ± 6.4 pmol•min −1 •mg −1 microsomal protein) versus the combined IM 2C19 + PM 2C19 groups (10.1 ± 5.3 pmol•min −1 •mg −1 microsomal protein; Fig. 4B ).
