Extended Data Fig. 10: Principal component analysis of EAS samples.
From: Comparative genetic architectures of schizophrenia in East Asian and European populations
a, EAS samples mapped to the global principal components created using 1000 Genomes Project Phase 1 samples. b, EAS cases and controls mapped respectively to principal components created using all EAS samples in this study. Populations were inferred from sample recruitment locations. a-b, n EAS controls = 17,261; cases = 14,607. Samples from stages 1 and 2 that have individual-level genotypes were included (before the removal of population outliers).
