Associations between SNPs of MTHFR, MTR, MTRR, DNMT1, and ALDH2 genes and cancers of the esophagus, stomach, and liver.

1: Semi-Bayes odds ratio (SBOR) adjusted for age (5-year categories and deviation from stratum mean) and sex.2: SBOR further adjusted for residency (city, rural), alcohol drinking frequency, smoking pack-years, BMI, education, H. pylori infection (in stomach cancer analyses), HBsAg (in liver cancer analyses), and plasma AFB1 levels (in liver cancer analyses), based on the assumption that genotype did not affect any of these variables.*: One-sided semi-Bayes P-values; the posterior probability that the point estimate is on the wrong side of the null [26], [27].†: P-value from Chi-Square test for trend.Associations between SNPs of MTHFR, MTR, MTRR, DNMT1, and ALDH2 genes and cancers of the esophagus, stomach, and liver.
