Summary ORs for Effects of PDE4D SNPs in Seven Populations
(A) Summary ORs for rs1588265 are 0.85 (95% CI: 0.77, 0.93) among all populations and 0.88 (95% CI: 0.83, 0.94) among replication populations.
(B) Summary ORs for rs1544791 are 0.85 (95% CI: 0.78, 0.94) among all populations and 0.89 (95% CI: 0.84, 0.94) among replication populations. Boxes are at the mean OR for each study, and their size is proportional to study size. Gray bars represent 95% CIs. The summary OR (diamond) was estimated with the DerSimonian-Laird random-effects model.
