Figure 2. Forest plot of overall cancer risk of different cancer types associated with ERCC5 Asp1104His polymorphism (His/His vs. Asp/His + Asp/Asp) by the fixed effects for each of the 44 published studies.

For each study, the estimates of OR and its 95% CI were plotted with a box and a horizontal line. The symbol filled diamond indicates pooled OR and its 95% CI.
