Subsetting PGC1.5 and UKB by sex showed a high genetic correlation between women and men for UKB (rg = 1.03, P = 1.6 × 10−5), but no significant genetic correlation between women and men in PGC1.5, which was expected, since h2SNP in PGC1.5 men is not significant. Next, focusing on PGC1.5 women only, a comparison to UKB showed significant genetic correlations with the overall UKB (rg = 0.46, P = 0.0004) and UKB women (rg = 0.46, P = 0.0008), and a slightly lower, but marginally significant correlation with the smaller UKB male data (rg = 0.44, P = 0.052).
