      ]. Several groups investigated the effects of anti-diabetic medications on the risk of CRC. However, the effects of newer agents, especially dipeptidyl peptidase 4 inhibitors (DPP4i) and sodium-glucose co-transporter 2 inhibitors (SGLT2i), received less attention. To compare the risks of incident CRC amongst DPP4i and SGLT2i users, we conducted the present study using a large territory wide cohort in Hong Kong consisting of all type 2 diabetes mellitus (T2DM) patients on any of the two medication classes.
