INS and polycystic ovary syndrome: Fasting secretion was predicted (r2 = 0.46; p<0.0001) by having PCOS (coefficient 17; 95%CI 10.5–2.35), being obese (coefficient 15.7; 95%CI 12.3–19), and insulin resistant (coefficient 26.9; 95%CI 22–31.8); total insulin secretion by having PCOS (coefficient 14; 95%CI 10.8–17.4), and being insulin resistant.
