Stratification analysis of the variant number of genotypes by selected variables in PCa patients and controls.

Bold-faced values indicate significant difference.*Two-sided χ2 test for either genotype distributions or allele frequencies between the cases and controls.†Adjusted for age, smoking status, drinking status and family history of cancer in logistic regression model; 95% CI: 95% confidence interval.‡The 0–4 represents the numbers of risk alleles within the combined genotypes; the risk alleles used for the calculation were the rs2295080T and rs7254617A alleles.
