Statistical analysis was performed by using JMP. Fisher’s exact test was used for associations between methylation status or immunostaining of PYCARD and clinicopathological parameters. A two-tailed Student -test was used for associations between methylation status or immunostaining of PYCARD and PSA. aCase no. 37 was excluded from this analysis because postoperative PSA levels did not drop to undetectable levels (0.2 ng/ml).
