Logistic regression analyses of associations between <i>NAT2</i> rs1041983 C>T, rs11780884 A>G, rs11996129 T>C, rs12674710 C>A, rs1390359 C>A, rs1390360 G>A, rs1565684 T>C, rs1799930 G>A, rs1799931 G>A and rs4540438 A>C polymorphisms and risk of ESCC.

aAdjusted for age, sex, smoking status and alcohol consumption; Bonferroni correction was performed to correct the p value (pcorrect); For the 10 NAT2 SNPs, pcorrect>0.05 in all comparison models; Bold values are statistically significant (p<0.05).
