  1. 1) B = difference of means
  2. 2) cause of death (cancer, CHF, COPD or combination of those; cancer is reference group), age of GP, working hours, interest in palliative care, and estimation of own capacity were included in the model as possible confounders
  3. 3) Effects of continuous variables are assessed as one unit offsets from the mean
  4. 4) OR = odds ratio
