  1. *Min-max: 0–100
  2. § Indicates clinical significant change measured from baseline, i.e. a change of > 10 points
  3. p-value significant at ≤ 0.05, ns = not significant.
  4. Effect size (ES) of change was calculated as mean change from baseline, divided by the standard deviation of change. Criteria: trivial 0 to < 0.20; small 0.20 to < 0.50; moderate 0.50 to < 0.80; and large ≥ 0.80
