  1. HRQOL = health related quality of life; OR = Odds ratio; CI = confidence interval;
  2. BP = Bodily pain; GH = General health.
  3. aFor HRQOL BP and GH scores, odd ratios per SD increase were calculated.
  4. bOnly variables with P < 0.05 were included in the model.
  5. cNagelkerke R2 is the variance of in the dependent variable (recent 2-week physician visit) explained by all independent variables included in the regression model.
  6. dThe independent contribution of each cluster of predictors to the variation in two-week physician visit was calculated as individual corresponding R2 change/total R2 change in the final model × 100%.
