  2. **The score for SF-36 ranges from 0 to 100 where 100 indicates a high HRQOL.
  3. ***The QOLS score ranges from 16 to 112 where 112 indicates a high GQOL.
  4. PCS = physical component summary, MCS = mental component summary, QOLS = quality of life scale.
  5. The full model included all of the selected variables entered into the model while the final model included variables in the final step using the backward procedure.
