Abstract

Background The effects of sodium-glucose co-transporter-2 (SGLT2) inhibitors on kidney failure, particularly the need for dialysis or transplantation or death due to kidney disease, is uncertain. Additionally, previous studies have been underpowered to robustly assess heterogeneity of effects on kidney outcomes by different levels of estimated glomerular filtration rate (eGFR) and albuminuria. We aimed to do a systematic review and meta-analysis to assess the effects of SGLT2 inhibitors on major kidney outcomes in patients with type 2 diabetes and to determine the consistency of effect size across trials and different levels of eGFR and albuminuria. Methods We did a systematic review and meta-analysis of randomised, controlled, cardiovascular or kidney outcome trials of SGLT2 inhibitors that reported effects on major kidney outcomes in people with type 2 diabetes. We searched MEDLINE and Embase from database inception to June 14, 2019, to identify eligible trials. The primary outcome was a composite of dialysis, transplantation, or death due to kidney disease. We used random-effects models to obtain summary relative risks (RRs) with 95% CIs and random-effects meta-regression to explore effect modification by subgroups of baseline eGFR, albuminuria, and use of renin–angiotensin system (RAS) blockade. This review is registered with PROSPERO (CRD42019131774). Findings From 2085 records identified, four studies met our inclusion criteria, assessing three SGLT2 inhibitors: empagliflozin (EMPA-REG OUTCOME), canagliflozin (CANVAS Program and CREDENCE), and dapagliflozin (DECLARE–TIMI 58). From a total of 38 723 participants, 252 required dialysis or transplantation or died of kidney disease, 335 developed end-stage kidney disease, and 943 had acute kidney injury. SGLT2 inhibitors substantially reduced the risk of dialysis, transplantation, or death due to kidney disease (RR 0·67, 95% CI 0·52–0·86, p=0·0019), an effect consistent across studies ( I 2 =0%, p heterogeneity =0·53). SGLT2 inhibitors also reduced end-stage kidney disease (0·65, 0·53–0·81, p<0·0001), and acute kidney injury (0·75, 0·66–0·85, p<0·0001), with consistent benefits across studies. Although we identified some evidence that the proportional effect of SGLT2 inhibitors might attenuate with declining kidney function (p trend =0·073), there was clear, separate evidence of benefit for all eGFR subgroups, including for participants with a baseline eGFR 30–45 mL/min per 1·73 m 2 (RR 0·70, 95% CI 0·54–0·91, p=0·0080). Renoprotection was also consistent across studies irrespective of baseline albuminuria (p trend =0·66) and use of RAS blockade (p heterogeneity =0·31). Interpretation SGLT2 inhibitors reduced the risk of dialysis, transplantation, or death due to kidney disease in individuals with type 2 diabetes and provided protection against acute kidney injury. These data provide substantive evidence supporting the use of SGLT2 inhibitors to prevent major kidney outcomes in people with type 2 diabetes. Funding None.

  • The benefits of SGLT2 inhibitors were highly consistent in people with and without type 2 diabetes.

    “The benefits were highly consistent in persons both with and without T2D; however, because persons with T2D had higher absolute risk, they experienced a greater absolute benefit with SGLT2is vs placebo.”

    From American Association of Clinical Endocrinology Clinical Practice Guideline: Developing a Diabetes Mellitus Comprehensive Care Plan-2022 Update. (2022) · cites this paper as [457]

    The Discussion reports kidney benefits from SGLT2 inhibitors in people with type 2 diabetes. It says trials enrolling people with and without type 2 diabetes were still underway, so this paper does not establish that benefits were highly consistent between those groups. Page numbers are unavailable in our copy. (LLM, conf=0.87)

  • Subgroup meta-analyses based on participants' kidney function indicated that the salutary effects of SGLT2i on MACE, cardiovascular death or hospitalization for heart failure, and a composite kidney outcome do not significantly differ among subgroups based on eGFR.

    “Subgroup meta-analyses based on participants ' kidney function indicated that the salutary effects of SGLT2i on MACE, cardiovascular death or HHF, and a composite kidney outcome (substantial loss of kidney function, end-stage kidney disease, or death due to kidney disease) do not signi fi cantly differ among subgroups based on eGFR (142,252).”

    From Management of Hyperglycemia in Type 2 Diabetes, 2022. A Consensus Report by the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) (2022) · cites this paper as [252]

    The Overall section reports benefits for the composite kidney outcome across eGFR subgroups, with no significant heterogeneity in the below-60 versus 60-or-higher comparison (p=0.33), although it notes a possible trend toward smaller relative benefits at lower eGFR. The paper does not report corresponding eGFR-subgroup findings for MACE or cardiovascular death or hospitalization for heart failure. Page numbers are not available in our copy. (LLM, conf=0.88)

  • Patients with chronic kidney disease and type 2 diabetes have high residual cardiorenal morbidity and mortality, despite current therapies.

    “Patients with chronic kidney disease (CKD) and type 2 diabetes have high residual cardiorenal morbidity and mortality, despite current therapies,1–5”

    From Cardiovascular and kidney outcomes with finerenone in patients with type 2 diabetes and chronic kidney disease: the FIDELITY pooled analysis (2022) · cites this paper as [4]

    The Introduction says that residual kidney risk remains high despite recommended ACE inhibitor or ARB treatment for people with type 2 diabetes who have, or are at risk of, kidney disease. The Results include cardiovascular or kidney death in a composite outcome, but the paper does not establish the claimed high residual cardiovascular morbidity and mortality in patients with both CKD and type 2 diabetes. (LLM, conf=0.83)

  • Evidence from combined major SGLT2 inhibitor trials suggests kidney and cardiovascular benefits are consistent irrespective of baseline albuminuria, including in patients with normal albumin excretion.

    “Evidence from combined major SGLT2i trials, however, suggests that kidney and cardiovascular benefits are consistent irrespective of baseline albuminuria (56), including in patients with normal albumin excretion, as reflected in the KDIGO recommendation and consensus statement supporting SGLT2i use in most patients with T2D and CKD (2).”

    From Diabetes management in chronic kidney disease: a consensus report by the American Diabetes Association (ADA) and Kidney Disease: Improving Global Outcomes (KDIGO) (2022) · cites this paper as [56]

    The Overall results report no evidence that the effect on the composite kidney outcome differed across baseline albuminuria groups. The Data analysis section includes a normal-albuminuria group (UACR <30 mg/g). The cited analysis does not establish that cardiovascular benefits were consistent across those groups. (LLM, conf=0.88)

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-11.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-11.

Cited sources are checked by gpt-6-sol.

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.
