Generalizability of findings from cardiovascular outcomes trials (CVOTs) to patients with type 2 diabetes (T2D) in clinical practice is unknown. We assessed the proportions of patients in the Diabetes Collaborative Registry who would have met enrolment criteria for pivotal CVOTs of sodium-glucose co-transporter-2 inhibitors (SGLT-2is): EMPA-REG OUTCOME, CANVAS, DECLARE and VERTIS CV. In 172 643 patients, mean [standard deviation (SD)] age and HbA1c were 68.1 (11.8) years and 7.8% (2.2), respectively; 56.8% of patients were men and SGLT-2i use was 4.4%. Atherosclerotic cardiovascular disease (ASCVD) prevalence was 64.3% and mean 10-year ASCVD risk was 28.6% in patients without ASCVD. Proportions of patients eligible for CVOTs ranged from 26% (EMPA-REG OUTCOME) to 44% (DECLARE); 48% of patients were ineligible for all CVOTs. Mean (SD) ASCVD risk was 25.4% (22.6), 32.1% (20.6) and 37.7% (19.4) in patients eligible for no, one or two CVOTs, respectively. SGLT-2i use was low in patients eligible for no CVOTs (3.5%) and at least one CVOT (5.2%). In conclusion, applicability of CVOT results to patients with T2D in clinical practice varies based on trial eligibility criteria.
