  1. HC healthy controls, PTSD post-traumatic stress disorder, TBI traumatic brain injury.
  2. aHOMA-IR (insulin resistance) is calculated by (glucose Ă— insulin)/22.5.
  3. bMetabolic syndrome is defined by at least 3 of the following 5 criteria: 1) fasting glucose ≥ 110 mg/dL, 2) abdominal obesity, based on waist circumference (WC) of > 40 inch (for men), or WC > 35 (for women), 3) TGs ≥ 150 mg/dL, 4) HDL cholesterol < 40 mg/dL (for men) or HDL < 50 mg/dL (for women), and 5) systolic blood pressure ≥ 130 or diastolic blood pressure ≥ 85 mmHg.
  4. *p < 0.05 for PTSD vs HC, TBI vs HC, or PTSD with TBI vs HC.
  5. #p < 0.05 for PTSD vs TBI.
