Clinical Interpretation

• What do the results mean?
• What is the clinical relevance of a particular
  score for QoL?
• How important are the observed changes in your
  patients QoL?
• If one group has a worse or better QoL than
  another group, are the differences large enough
  to be important?
• If QoL changes over time, how large do the
  changes need to be before they are detected?
• What magnitude of change is big enough to be
  considered important
• Do any differences between groups diminish over
  time?
