Values are presented as mean ± standard deviation (SD). P: resulted from comparisons within groups by paired t-test
P ^†: resulted from comparisons between two groups by independent t-test. P ^††: resulted from comparisons mean changes between two groups by Univariate analysis of covariance after adjusting for energy intake and BMI.
