  1. Therapy variables were calculated starting from 12 months before the index date, unless otherwise indicated. Pre-existing conditions were calculated with all available data up to the index date. Clinical-laboratory data refer to the visit closest to the index date. Absolute SMD values are shown
  2. *Standardized mean differences (positive if SGLT2i greater; “< 0.01” if |SMD| < 0.01)
  3. **Chi-squared test for dichotomous variables (expressed as %), Mann–Whitney’s U test otherwise
  4. aTime interval between the first available claim and the index date
  5. bTime interval between the first claim or exemption from co-payment indicating diabetes and the index date
  6. cComputed using all available data up to the index date
