None of the adverse events reported by patients (N = 65) was influenced by the patients’ CYP1A2 expression (P > 0.1), and CYP3A4 expression had a marginally significant effect on constipation [47.1% in normal/high CYP3A4 expressers, 71.4% in low CYP3A4 expressers, OR = 3.6 (95%CL = 0.9–14.1), Wald ChiSq = 3.4, N = 65, P = 0.06] (Table 3 ), indicating that patients expressing CYP3A4 at low level tended to report constipation more frequently.
