From: Apparent latent structure within the UK Biobank sample has implications for epidemiological analysis
The relationship between polygenic scores (PS; right-hand label) and geographical terms (left-hand label) within the UK Biobank sample. Tiles are shaded by p value testing the null hypothesis of no association between PS and geographical term, where p = 0 is shaded in black and p = 2e−16 is shaded in red. Statistical adjustment was performed as follows: model 1: no adjustment; model 2: adjustment for genotyping array only; model 3: adjustment for genotyping array, 10 principal components (PCs) and study participation centre; model 4: adjustment for genotyping array, 40 PCs and study participation centre
