  1. * P-values calculated by using the chi-square test
  2. 1 Reduction of ≥ 2 points (30%) from baseline [21]
  3. 2 Reduction of ≥ 8.8 points or 14% from baseline [25]
  4. 3 Reduction of ≥ 3 PSQI points considered a treatment response [26]
  5. 4 Increase of 6.5 points (SF-physical) and 7.9 points (SF-mental) [12]
