  1. These trials cannot be directly compared, owing to differences in study design, populations and methodology. *Post hoc analysis for lower limb amputation, which was not a prespecified outcome in EMPA-REG OUTCOME. †All amputation; data for lower limb amputation not provided. ‡Diabetic ketoacidosis events pooled across CANVAS and CANVAS-R, and 100 mg and 300 mg doses of canagliflozin. Pooled cohort size indicates the intention to treat population. Cana 100/300, canagliflozin 100/300 mg; Empa 10/25, empagliflozin 10/25 mg
