Abstract

Objective: To determine whether the combined use of glucagon-like peptide-1 (GLP-1) receptor agonists and sodium-glucose cotransporter-2 (SGLT-2) inhibitors is associated with a decreased risk of major adverse cardiovascular events and serious renal events compared with either drug class alone among patients with type 2 diabetes, and to assess the effect of the combination on the individual components of major adverse cardiovascular events, heart failure, and all cause mortality. Design: Population based cohort study using a prevalent new-user design, emulating a trial. Setting: UK Clinical Practice Research Datalink linked to Hospital Episode Statistics Admitted Patient Care and Office for National Statistics databases. Participants: Two prevalent new-user cohorts were assembled between January 2013 and December 2020, with follow-up until the end of March 2021. The first cohort included 6696 patients who started GLP-1 receptor agonists and added on SGLT-2 inhibitors, and the second included 8942 patients who started SGLT-2 inhibitors and added on GLP-1 receptor agonists. Combination users were matched, in a 1:1 ratio, to patients prescribed the same background drug, duration of background drug, and time conditional propensity score. Main outcome measures: Cox proportional hazards models were fitted to estimate the hazard ratios and 95% confidence intervals of major adverse cardiovascular events and serious renal events, separately, comparing the GLP-1 receptor agonist-SGLT-2 inhibitor combination with the background drug, either GLP-1 receptor agonists or SGLT-2 inhibitors, depending on the cohort. Secondary outcomes included associations with the individual components of major adverse cardiovascular events (myocardial infarction, ischaemic stroke, cardiovascular mortality), heart failure, and all cause mortality. Results: Compared with GLP-1 receptor agonists, the SGLT-2 inhibitor-GLP-1 receptor agonist combination was associated with a 30% lower risk of major adverse cardiovascular events (7.0 v 10.3 events per 1000 person years; hazard ratio 0.70, 95% confidence interval 0.49 to 0.99) and a 57% lower risk of serious renal events (2.0 v 4.6 events per 1000 person years; hazard ratio 0.43, 0.23 to 0.80). Compared with SGLT-2 inhibitors, the GLP-1 receptor agonist-SGLT-2 inhibitor combination was associated with a 29% lower risk of major adverse cardiovascular events (7.6 v 10.7 events per 1000 person years; hazard ratio 0.71, 0.52 to 0.98), whereas serious renal events generated a wide confidence interval (1.4 v 2.0 events per 1000 person years; hazard ratio 0.67, 0.32 to 1.41). Secondary outcomes generated similar results but with wider confidence intervals. Conclusions: In this cohort study, the GLP-1 receptor agonist-SGLT-2 inhibitor combination was associated with a lower risk of major adverse cardiovascular events and serious renal events compared with either drug class alone.

  • In a population-based cohort study, addition of a GLP-1 RA on top of SGLT2 inhibitor treatment was associated with a 30% lower risk of major adverse cardiovascular events and 57% lower risk of serious kidney events compared with GLP-1 RA therapy alone after a median follow-up of 9 months.

    “The addition of a GLP-1 RA on top of SGLT2 inhibitor treatment was associated with a 30% lower risk of major adverse cardiovascular events and 57% lower risk of serious kidney events compared with GLP-1 RA therapy alone after a median follow-up of 9 months.”

  • In the same cohort study, addition of an SGLT2 inhibitor on top of GLP-1 RA was associated with a 29% lower risk of major adverse cardiovascular events compared with SGLT2 inhibitor alone.

    “The addition of an SGLT2 inhibitor on top of GLP-1 RA was associated with a 29% lower risk of major adverse cardiovascular events compared with SGLT2 inhibitor alone.”

    From 11. Chronic Kidney Disease and Risk Management: Standards of Care in Diabetes—2026 (2026) · cites this paper as [146]

    The Results section (GLP-1 receptor agonist–SGLT-2 inhibitor combination versus SGLT-2 inhibitors; page unavailable) reports a 29% lower risk of major adverse cardiovascular events for combination treatment versus SGLT-2 inhibitors alone. But that comparison concerns adding a GLP-1 receptor agonist to SGLT-2 inhibitor treatment. The Results section reports a 30% lower risk, compared with GLP-1 receptor agonists alone, for the add-on direction stated in the claim. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • In the cohort study, when stratified based on history of kidney disease, use of combination treatment by individuals with a history of kidney disease was associated with a lower risk of major adverse cardiovascular events compared with those without kidney disease.

    “When stratified based on history of kidney disease, the use of combination treatment by individuals with a history of kidney disease was associated with a lower risk of major adverse cardiovascular events compared with those without kidney disease (146).”
  • The combination of GLP-1 receptor agonists and SGLT2 inhibitors is associated with a lower risk of major adverse cardiovascular events and serious kidney disease events compared with either drug class alone.

    “The authors concluded that the combination of both drug classes was associated with a lower risk of MACE and serious kidney disease events compared with either drug class alone.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
