Here, no association of PCOS and ApoB was found, though ApoB showed a trend to increase; this result differs from a study of young girls with PCOS, where elevated plasma apoB48-lipoprotein remnants were found to be highly associated with cardiometabolic risk and had ~2-fold elevated prevalence compared with girls without PCOS. This evidence concerns the gene APOB and polycystic ovary syndrome.
