  1. All continuous variables are expressed as median (interquartile range). Categorical variables represent number (%).
  2. IDU, intravenous drug users; MSM, men who have sex with men; FMD, flow-mediated dilatation; MD, mediated dilatation; IMT, intima-media thickness; IQR, interquartile range.
  3. APRI = [AST (U/L)/upper limit of normal (U/L)] × 100/platelets (109/L).
  4. FIB-4 = Age × AST (U/L)/[platelets (109/L) × ALT1/2 (U/L)]
  5. 1Lipodystrophy was defined as the presence of body-fat changes that could be clearly recognised by both the patient and the doctor.
  6. 2Metabolic syndrome was defined according to the new International Diabetes Federation criteria. by the existence of central obesity (waist circumference in females > 80 cm and in males > 94 cm in Europeans) plus two of the following factors: raised triglycerides (> 150 mg/dl), reduced HDL cholesterol (< 50 mg/dl in females and < 40 mg/dl in males), raised blood pressure (≥130/85 mm Hg), and raised fasting plasma glucose (> 100 mg/dl), or specific therapy for any of such conditions.
  7. 3P for the comparison between genotypes 1 and 4 with genotypes 2 and 3.
  8. 4The 10-year risk of developing myocardial infarction or coronary death was calculated for each patient with the Framingham equation.
