  1. a Variables are listed in the order in which they entered the equations. The results for the analyses with the MHAQ as dependent variable are not shown because only the baseline scores for the MHAQ entered the equation.
  2. b Proportion of variation these variables are able to account for in dependent variable scores.
  3. c NRS scales are scored from 0–10; 0 is no pain and fatigue,10 is the worst pain and fatigue.
  4. d RD-IPQ is scored from 0 to 100 where 100 is worst possible illness perceptions.
  5. e SF-36 is scored from 0 to100 where 100 is the best possible health.
