Abstract

BACKGROUND: In patients with type 2 diabetes, inhibitors of sodium-glucose cotransporter 2 (SGLT2) reduce the risk of a first hospitalization for heart failure, possibly through glucose-independent mechanisms. More data are needed regarding the effects of SGLT2 inhibitors in patients with established heart failure and a reduced ejection fraction, regardless of the presence or absence of type 2 diabetes. METHODS: In this phase 3, placebo-controlled trial, we randomly assigned 4744 patients with New York Heart Association class II, III, or IV heart failure and an ejection fraction of 40% or less to receive either dapagliflozin (at a dose of 10 mg once daily) or placebo, in addition to recommended therapy. The primary outcome was a composite of worsening heart failure (hospitalization or an urgent visit resulting in intravenous therapy for heart failure) or cardiovascular death. RESULTS: Over a median of 18.2 months, the primary outcome occurred in 386 of 2373 patients (16.3%) in the dapagliflozin group and in 502 of 2371 patients (21.2%) in the placebo group (hazard ratio, 0.74; 95% confidence interval [CI], 0.65 to 0.85; P<0.001). A first worsening heart failure event occurred in 237 patients (10.0%) in the dapagliflozin group and in 326 patients (13.7%) in the placebo group (hazard ratio, 0.70; 95% CI, 0.59 to 0.83). Death from cardiovascular causes occurred in 227 patients (9.6%) in the dapagliflozin group and in 273 patients (11.5%) in the placebo group (hazard ratio, 0.82; 95% CI, 0.69 to 0.98); 276 patients (11.6%) and 329 patients (13.9%), respectively, died from any cause (hazard ratio, 0.83; 95% CI, 0.71 to 0.97). Findings in patients with diabetes were similar to those in patients without diabetes. The frequency of adverse events related to volume depletion, renal dysfunction, and hypoglycemia did not differ between treatment groups. CONCLUSIONS: Among patients with heart failure and a reduced ejection fraction, the risk of worsening heart failure or death from cardiovascular causes was lower among those who received dapagliflozin than among those who received placebo, regardless of the presence or absence of diabetes.

  • In DAPA-HF, 55% of patients did not have diabetes at baseline, and the effect of dapagliflozin was similar at any hemoglobin A1c level.

    “Importantly, 55% of patients in this trial did not have diabetes at baseline, and the effect of dapagliflozin was similar at any hemoglobin A1c level.40”

    From CCS/CHFS Heart Failure Guidelines Update: Defining a New Pharmacologic Standard of Care for Heart Failure With Reduced Ejection Fraction (2021) · cites this paper as [40]

    The Discussion (p. 8) states that 55% of patients did not have type 2 diabetes and that dapagliflozin was as effective in those patients as in patients with diabetes. The Outcomes section (p. 6) likewise reports a generally consistent effect across prespecified subgroups, including patients without diabetes. Our copy does not establish that the effect was similar at every hemoglobin A1c level; comparing diabetes status does not establish that more specific claim. (LLM, conf=0.86)

  • In DAPA-HF, the secondary outcome of worsening kidney function occurred in 1.2% of the dapagliflozin arm and 1.6% of the placebo arm (HR 0.71; 95% CI 0.44-1.16), which was not statistically significant (P=0.17).

    “the secondary outcome of worsening kidney function (de fi ned as a sustained $ 50% reduction in eGFR, kidney failure, or death from kidney causes) occurred in 1.2% of the dapagli fl ozin arm and 1.6% of the placebo arm (HR: 0.71; 95% CI: 0.44 -1.16), which was not statistically signi fi cant ( P ¼ 0.17).”

    From KDIGO 2022 Clinical Practice Guideline for Diabetes Management in Chronic Kidney Disease (2022) · cites this paper as [100]

    The Outcomes section (p. 4) defines the renal composite as a sustained eGFR decline of at least 50%, end-stage renal disease, or renal death. The Outcomes results (p. 6) say its incidence did not differ between groups, supporting the claim of no statistically significant difference. The passages available from our copy do not establish the stated percentages, hazard ratio, confidence interval, or P value. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • In the DAPA-HF trial, major hypoglycemia, lower-limb amputation, and fracture occurred infrequently and incidences were similar between the 2 treatment groups.

    “In the DAPA-HF trial, major hypoglycemia, lower-limb amputation, and fracture occurred infrequently and the incidences were similar between the 2 treatment groups.”

    From KDIGO 2022 Clinical Practice Guideline for Diabetes Management in Chronic Kidney Disease (2022) · cites this paper as [100]

    The Discussion (p. 13) says major hypoglycemia was rare, and the Results (p. 2) say hypoglycemia-related adverse events did not differ between groups. The Outcomes section (p. 4) lists fractures and amputations among the prespecified safety analyses, but the passages found do not establish that those events were infrequent or had similar incidences between groups. (LLM, conf=0.82)

  • SGLT2 inhibitors reduce the incidence of heart failure and improve heart failure-related outcomes, including hospitalization for heart failure and heart failure-related symptoms, in people with diabetes with preserved or reduced ejection fraction.

    “SGLT2 inhibitors reduce the incidence of heart failure and improve heart failurerelated outcomes, including hospitalization for heart failure and heart failure-related symptoms, in people with diabetes with preserved or reduced ejection fraction (250,(255)(256)(257)(298)(299)(300)(301)(302)(303)(304)(305)(306).”

    From 10. Cardiovascular Disease and Risk Management: Standards of Care in Diabetes—2025 (2025) · cites this paper as [299]

    The Background (p. 2) says SGLT2 inhibitors reduce the risk of a first heart-failure hospitalization in people with type 2 diabetes. The Discussion (p. 8) reports fewer heart-failure hospitalizations and symptoms with dapagliflozin, but this trial enrolled patients with reduced ejection fraction, not preserved ejection fraction; its results therefore do not support that part of the claim. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • The lower risk of heart-failure hospitalization or cardiovascular death with dapagliflozin is consistent with the DECLARE-TIMI 58 and DAPA-HF trials.

    “The lower risk of hospitalization for heart failure or death from cardiovascular causes in the dapagliflozin group than in the placebo group is consistent with the results of two previous trials of dapagliflozin, the DECLARE-TIMI 58 (Dapagliflozin Effect on Cardiovascular Events-Thrombolysis in Myocardial Infarction 58) and DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure”

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.
