  1. Results are measured as logit-transformed utility scores. Utility scores range on a scale from 0 (equivalent to death) to 1 (equivalent to perfect health)
  2. Significant results are bolded
  3. The coefficients represent the change in the mean logit of utility scores when the predictor increases by one unit and the remaining covariates are held constant
