Principal components analysis of DNAme at the 162 significantly sex-differentially methylated CpGs. a Density plot of male (M, red curve) and female (F, yellow curve) samples along PC1 of the 162 sex-associated DMPs. b Scatterplot of PC1 versus PC2 of the discovery cohort; male (M) samples are plotted in red, and females (F) in yellow. c Significant associations between clinical variables and PC1 in a sex-stratified analyses. Linear regression R2 and p values are reported for each significant variable; a yellow arrow indicates significant association in females, and a red arrow indicates significant association in males. PC indicates principal component
