Associations of cumulative number of risk alleles with overall prostate cancer, and stratified by clinical features, age at diagnosis and family history of prostate cancer.

*The cutoff points for quartiles were determined based on the distribution of number of risk alleles among all controls; numbers in parenthesis represent the range of number of risk alleles for each quartile.Percentages represent row percents.†ORs and 95% CI were computed using logistic regression models adjusted for age; cases or controls with missing SNPs genotype data were excluded.‡ORs and 95% CI for clinical features of prostate cancer were computed using polytomous logistic regression adjusted for age. Cases or controls with missing SNPs genotype data or cases with missing clinical information for prostate cancer (n = 60) were excluded.
