  1. Reported as mean ± standard deviation or median (interquartile range).
  2. n – number; BMI – body mass index (kg/m2); HbA1c – glycated hemoglobin (%); BP – blood pressure; HDL – high-density lipoprotein (mg/dL); LDL – low-density lipoprotein (mg/dL); DEE – daily energy expenditure (kcal); PAL – physical activity level = total energy expenditure/resting energy expenditure; MVPA – moderate to vigorous physical activity (intensity >3 × resting energy expenditure) (min/day)
