  1. † Betas derived from ordinary least squares regression models, and odds ratios from multiple logistic regression models.
  2. ‡ Compared to reference group of 684 patients with "average disease severity". * = p < .05, ** = p < .01, *** = p < .001
  3. ¶ Scores on this scale range from 0 (worst health or function) to 100 (best health or function)
