a The genotyping success rate was 99.02% for rs7947978; b Adjusted for age, sex, smoking status and alcohol consumption (besides stratified factors accordingly) in a logistic regression model; Fisher exact test was performed when n ≤ 5; Bonferroni correction was performed to correct the p value, bold values are statistically significant (p < 0.0125).
