  1. The differences between means for patient groups tested at 12 months follow-up and the population norms
  2. aCalculated from the differences of two respective means (mean of group minus mean of normative value)
  3. bValue derived from a sample of 3072 healthy participants studied by Azman et al. Malaysian population norms as a reference point
  4. cMean difference is higher in value which indicates a better health score between the three groups
  5. dPositive value of mean differences was considered higher than the normative value
