^aBetween-group comparison of variables at baseline and after intervention from independent t test (for all variables)
^bBetween-group comparison of variables at baseline and after intervention from analysis of covariance (ANCOVA) in the adjusted models (adjusted for age, duration of disease, dietary intake of energy, macronutrients, antioxidant vitamins such as vitamins A, C, and E, physical activity and body mass index)
^cBetween-group comparisons mean changes of variables from Mann–Whitney U test (for fasting blood sugar (FBS)) and independent t test (for other variables)
