Fig. 2From: PASTRY: achieving balanced power for detecting risk and protective minor alleles in meta-analysis of association studies with overlapping subjectsPower difference between the original LS method and the LS method with correlation errors (LSE) for A risk (left) and B protective (right) alleles, respectively. The correlation errors \((\Delta r)\) were varied from 0.0 to 0.1, and the number of studies was varied from 2 to 10 for both situationsBack to article page
