  1. Data are presented as Mean ± SD; n = No of subjects
  2. a-b values within a row with different superscript letters differ (p < 0.05), as analysed by one-way ANOVA
  3. *p values were compared within each group from baseline using paired t test
  4. **p values were compared between groups
  5. 1)P values were derived from ANOVA, and Scheffe test was used to post hoc test
  6. 2)P values were derived from Kruskal-Wallis test, and Dunnett T3 test was used to post hoc test
