Figure 3. Stratified analysis based on the diﬀerent cancer sites for the association between microRNA-608 rs4919510 polymorphism and cancer risk using homozygote model (GG vs. CC). The squares and horizontal lines correspond to the study specific OR and 95% CI. The area of the squares reﬂects the weight (inverse of the variance). The diamond represents the summary OR and 95% CI.
