APOE and polycystic ovary syndrome: ApoE correlated positively with BMI in controls (r = 0.27, p = 0.01); correlated positively with total cholesterol in controls (r = 0.38, p = 0.0002) and PCOS (r = 0.59, p < 0.0001); correlated positively with TG in controls (r = 0.61, p < 0.0001) and PCOS (r = 0.62, p < 0.0001); correlated negatively with HDL-C in controls (r = −0.28, p = 0.014); and correlated positively with LDL-C in controls (r = 0.34, p = 0.003) and PCOS (r = 0.53 p < 0.0001) (Figure 4).
