XPC and posterior cortical atrophy: However, we observed no obvious association between XPC rs2228001 A/C variant and PCa risk in European populations (allelic contrast: OR = 0.94, 95% CI = 0.88 ‐ 1.01, Pheterogeneity = 0.033, P = .107; heterozygous contrast: OR = 0.95, 95% CI = 0.85 ‐ 1.06, P‐value for heterogeneity = 0.720, P = .333; dominant model: OR = 0.93, 95% CI = 0.84 ‐ 1.03, Pheterogeneity = 0.260, P = .179; recessive model: OR = 0.91, 95% CI = 0.80 ‐ 1.05, Pheterogeneity = 0.019, P = .199).
