  1. Regression coefficients (except the intercept) are exponentiated so that the interpretation for the coefficient is relative to the reference value, i.e. coefficient tells how many times larger (or smaller) the one-year costs are in the current group (on condition that other factors remain the same). For example, the predicted one-year cost for men with cerebrovascular complication (and with all factors in reference values) is 9663.62€ while the one-year cost for women is 0.85*9663.62 = 8214.077€
  2. NA Not Applicable
  3. P-values: ** p < 0.01, * p < 0.05
  4. a Corresponds with the costs of 75-year-old men with newly diagnosed T2D, no coexisting comorbidities and who will stay alive a period of one year since the complication event
  5. b A relative difference in treatment costs between men and women
