Effects of Losartan on Renal and Cardiovascular Outcomes in Patients with Type 2 Diabetes and Nephropathy
Open accessAbstract
BACKGROUND: Diabetic nephropathy is the leading cause of end-stage renal disease. Interruption of the renin-angiotensin system slows the progression of renal disease in patients with type 1 diabetes, but similar data are not available for patients with type 2, the most common form of diabetes. We assessed the role of the angiotensin-II-receptor antagonist losartan in patients with type 2 diabetes and nephropathy. METHODS: A total of 1513 patients were enrolled in this randomized, double-blind study comparing losartan (50 to 100 mg once daily) with placebo, both taken in addition to conventional antihypertensive treatment (calcium-channel antagonists, diuretics, alpha-blockers, beta-blockers, and centrally acting agents), for a mean of 3.4 years. The primary outcome was the composite of a doubling of the base-line serum creatinine concentration, end-stage renal disease, or death. Secondary end points included a composite of morbidity and mortality from cardiovascular causes, proteinuria, and the rate of progression of renal disease. RESULTS: A total of 327 patients in the losartan group reached the primary end point, as compared with 359 in the placebo group (risk reduction, 16 percent; P=0.02). Losartan reduced the incidence of a doubling of the serum creatinine concentration (risk reduction, 25 percent; P=0.006) and end-stage renal disease (risk reduction, 28 percent; P=0.002) but had no effect on the rate of death. The benefit exceeded that attributable to changes in blood pressure. The composite of morbidity and mortality from cardiovascular causes was similar in the two groups, although the rate of first hospitalization for heart failure was significantly lower with losartan (risk reduction, 32 percent; P=0.005). The level of proteinuria declined by 35 percent with losartan (P<0.001 for the comparison with placebo). CONCLUSIONS: Losartan conferred significant renal benefits in patients with type 2 diabetes and nephropathy, and it was generally well tolerated.

“In this regard, it should be noted that in related studies in patients with type 1 and type 2 diabetes, 1,28,29 the benefits of captopril or irbesartan were not tested in the presence of concurrent calcium-channel-antagonist therapy.”
What the sources say
- Not checked — no full text of the sourcecites [1] source
- Supportedcites [28] source
The Randomization and Treatment Plan states that calcium-channel blockers were discontinued before screening and excluded as additional antihypertensive treatment. Irbesartan and the calcium-channel blocker amlodipine were assigned as separate regimens, so this type 2 diabetes study did not test irbesartan's benefit with concurrent calcium-channel-blocker therapy. The captopril study in type 1 diabetes is covered by the sentence's other citations, not this source. (LLM, conf=0.92)

“The mean follow-up time was 3.4 years (42 months).”
Patients with prior heart failure were both excluded and included
MinorThe eligibility criteria excluded anyone with a history of heart failure before enrollment, but the paper later says 88 patients had preexisting heart failure at randomization. This affects the description of the population used for the heart-failure analysis.
“who had any history of heart failure before enrollment.”
“There were 88 patients (44 in each group) who had preexisting heart failure at the time of randomization.”

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.
A language model drew the claims from the paper on 2026-10-16, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-16 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (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.
