3.3 Subgroup analysis of p16 methylation in PCa versus benign prostatic lesions According to ethnicity (Caucasians and Asians) and testing method (methylation-specific polymerase chain reaction [MSP] and non-MSP), subgroup analysis of ethnicity showed a trend toward the correlation between p16 methylation and Caucasians with PCa (OR = 4.16, 95% CI = 0.91–19.16, P = .067) (Fig. 3 ).
