Associations of PD-1 and PD-L1 gene polymorphisms with cancer risk: a meta-analysis based on 50 studies
Figure 3. Forest plot for the association between PD-1.9 gene polymorphism and cancer risk under all the five models. For each publication, the estimation of OR and its 95% CI was plotted with a box and a horizontal line. The diamonds represented the pooled ORs and 95% CIs. (A) Allele model; (B) homozygote model; (C) heterozygote model; (D) dominant model; (E) recessive model.
