Table 2 reports how often each training sample (EA or training ADM) provided a tag SNP having higher LD with the true causal SNP in the test ADM dataset. The tag SNPs in CEU and the training ADM population were often the same (46-50% of the time). When they differed, the tag SNP identified in the training ADM population was usually a better tag of the causal SNP in the test ADM population.
