  • *p Value (two-sided) determined from either a χ2 test for non-ordered categories for categorical characteristics or the Wilcoxon two-sample test for continuous characteristics.

  • †Prediabetes defined as HbA1c between 5.7% and 6.4% and/or fasting glucose between 100 and 125 mg/dL.

  • BMI, body mass index; CVD, cardiovascular disease; HbA1c, glycated haemoglobin; NAFLD, non-alcoholic fatty liver disease.
