A significant association was detected between the SHMT1 C1420T polymorphism and NHL risk under the allelic comparison. The boxes and horizontal lines correspond to the estimates of odds ratio (OR) and 95% confidence interval (CI) for each study. The diamond indicates the pooled OR and 95% CIBack to article page
