  2. P values superscript with “a” is calculated using repeated measures ANOVA test for comparing different time points; P values superscript with “b” is calculated using independent t test for comparing between groups at each time points
  3. αSignificantly different compared with post1 within the group
  4. £Significantly different compared with pre 2 within the group
