Meta-analysis of ADH1B and ALDH2 polymorphisms and esophageal cancer risk in China

Figure 1 Forest plot shows the odds ratios and confidence intervals of the association. A: Between arginine (Arg)/histidine (His) and His/His genotype of alcohol dehydrogenase-1B (ADH1B) His47Arg polymorphism; B: Between Arg/Arg and His/His genotype of ADH1B gene His47Arg polymorphism; C: Between glutamate (Glu)/lysine (Lys) and Gly/Glu genotype of aldehyde dehydrogenase-2 (ALDH2) Glu487Lys polymorphism; D: Between Lys/Lys and Glu/Glu genotype of ALDH2 Glu487Lys polymorphism. OR: Odds ratio; CI: Confidence interval.
