INS and polycystic ovary syndrome: Group D exhibited the highest insulin resistance (median HOMA-IR = 3.47, QUICKI = 0.32, insulin = 15.32 μIU/mL), followed by Group C (HOMA-IR = 2.65, QUICKI = 0.33, insulin = 11.39 μIU/mL), indicating severe metabolic dysregulation in phenotypes with ovulatory dysfunction and polycystic ovaries.
