All values are expressed as mean ± SD. All the comparisons were obtained by paired t-test with 0 wk values or Wilcoxon matched-pairs signed-rank test depending on the distribution of the data. p values were obtained from the difference among groups. ∗Data are not assumed to be Gaussian distribution.
