INS and prediabetes syndrome: Importantly, the clusters also associated differently with conditions reflecting clinical cut-offs for differential glucose control, i.e., prediabetes (fasting HbA1c ≥ 5.7% and fasting blood glucose > 100 mg/dL, p = 0.01 [30], insulin resistance (p = 6.5×10−7), (Matsuda index ≤ 2.5), and glucose control (p = 6.6×10−5) (normal, impaired, or diabetic [30,31]) using a Chi-squared test.
