1. Per user data derive from one-step and two-step Generalized Linear Models with gender as the coefficient of interest.
2. Patient level data are means based on recycled predictions with gender as the coefficient of interest.
3. Significance at the patient level is estimated based on p1 and p2 in the two-part models and based on p2 in the one-step models.
4. p1 derives from the logistic model (approach 2, step 1) and p2 derives from the gamma model (approach 2, step 2 and approach 1).
5. * Results of model estimation; the addition of mean costs per category yields slightly different figures.
