Meta-analysis of the association between rs1042714 and GD measured by allele frequency data. OR (black squares) and 95% CI (bar) are shown for each study. The pooled ORs and their 95% CIs are represented by the shaded diamonds. Summary ORs are given for each ethnic group as well as all groups combined. The symbol n indicates the total number of C alleles, and N indicates the total number of C plus G alleles. A) DerSimonian-Laird OR meta-analysis (random effects) of the three studies; B) Mantel-Haenszel OR meta-analysis (fixed effects) of the two European studies.
