  1. Combination drugs were included in each drug class by corresponding ingredients.
  2. AE adverse event, CI confidence interval, GLP-1RA glucose like peptide-1 receptor analogues, SGLT2 inhibitors sodium-glucose co-transporter 2 inhibitors, DPP4i dipeptidyl peptidase 4 inhibitors.
  3. aReporting rate per 10,000 people was calculated over the total number of drug users of each class.
  4. bReporting ratio = reporting rate of women/ reporting rate of men.
