SMD in vitamin B-12 (A) and folate (B) between subjects with GG and CC genotypes for the rs1801198. The calculated summary effects are denoted by the solid diamonds at the bottom of the forest plots, the widths of which represent the 95% CIs. For each study, the gray box and the horizontal line denote the central value of the effect size and its 95% CI, respectively. DL, DerSimonian and Laird procedure; EUR, study that included European-descent subjects; RE, random-effects model; SMD, standardized mean difference.
