Fasting glucose, fasting insulin, and HOMA-IR higher vs controls; HOMA-IR higher in patients with poorly controlled than with well-controlled CAH; correlations of fasting insulin and HOMA-IR with homocysteine, left ventricular mass index, carotid artery intima–media thickness, and mitral deceleration time. Here, INS is linked to congenital adrenal hyperplasia.
