Sacubitril/Valsartan versus Enalapril or Losartan at Maximum Doses in Heart Failure with Reduced Ejection Fraction: Real-World Data.
Observational study in Arquivos brasileiros de cardiologia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSacubitril/valsartan reduced mortality and hospitalizations in patients with heart failure with reduced ejection fraction (HFrEF) compared to enalapril in pivotal clinical trials. However, real-world data under optimized dosing remain limited.
objectiveTo compare the outcomes of HFrEF patients treated with sacubitril/valsartan versus either enalapril or losartan at guideline-recommended maximum dosages.
methodsWe analyzed data from an observational heart failure cohort (n = 2,314) including patients receiving care between August 2010 and September 2024 at six public hospitals in a large metropolitan area. The primary analysis included 254 HFrEF patients receiving the guideline-recommended maximum dosages of the investigated drugs. A sensitivity analysis included 452 patients receiving any submaximal dosages. The primary outcome was combined hospitalization or death. Baseline differences were adjusted using propensity score matching. A p-value < 0.05 was considered significant.
resultsAmong 254 HFrEF patients (mean age 63.6 ± 12.3 years, 61.4% male), 115 received sacubitril/valsartan 97/103mg twice daily, 33 enalapril 20 mg twice daily, and 106 losartan 100 mg daily. Over the median follow-up of 23.9 months (interquartile range 11.9-41.1), there were 70 primary endpoint events (56 first hospitalizations, 32 deaths). Compared to equivalent dosages of enalapril or losartan, sacubitril/valsartan was not associated with significant reductions in combined hospitalization or death (odds ratio 0.650, 95% confidence interval 0.354-1.195, p = 0.165), but it was associated with functional status improvement (odds ratio 3.902, 95% confidence interval 1.745-8.726, p = 0.001).
conclusionThis real-world study did not demonstrate significant reductions in hospitalization or mortality for sacubitril/valsartan compared with enalapril or losartan at guideline-recommended maximum dosages; however, sacubitril/valsartan was associated with improved functional status.
