CYP2R1 and hepatocellular carcinoma: In the combined analyses of these cohorts, the strongest association with HCV-induced HCC was found for GC (P = 0.007, OR = 1.56, 95% CI = 1.12–2.15) and DHCR7 (P = 0.003, OR = 1.42, 95% CI = 1.13–1.78), whereas CYP2R1 was almost significantly associated with HCV-induced HCC (P = 0.07, OR = 1.13, 95% CI = 0.99–1.28).
