Distribution of genotypes of <i>MDC1</i> and associations with the risk of lung cancer.

aThe genotype distributions of above SNPs in controls were all in Hardy-Weinberg equilibrium (P>0.05). bThe frequency distribution of genotypes of SNPs between cases and controls by the chi-square test. cAdjusted in a logistic regression model that included age, sex, smoking status, drinking status, and family history of cancer.
