Sacubitril/Valsartan vs Enalapril in Heart Failure Due to Chagas Disease: An Open-Label, Multicenter Randomized Clinical Trial.
Trial report in JAMA, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04023227 (A Multicenter, Prospective, Randomized, Open-label, Blinded-endpoint, Phase 4 Study to Evaluate the Efficacy and Safety of Sacubitril/Valsartan Compared With Enalapril on Morbidity, Mortality, and NT-proBNP Change in Patients With Chronic Chagas' Cardiomyopathy.

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

Abstract
Importance: The efficacy and safety of guideline-recommended treatments for heart failure (HF) are uncertain in patients with Chagas disease. Objective: To evaluate the efficacy and safety of the angiotensin receptor-neprilysin inhibitor sacubitril/valsartan in patients with HF with reduced ejection fraction due to Chagas disease. Design, Setting, and Participants: From December 10, 2019, through September 13, 2023, patients with HF, confirmed diagnosis of Chagas disease, left ventricular ejection fraction of 40% or less, and N-terminal pro-B-type natriuretic peptide (NT-proBNP) of 600 pg/mL or greater (or B-type natriuretic peptide [BNP] ≥150 pg/mL) or 400 pg/mL or greater (or BNP ≥100 pg/mL) if hospitalized for HF within the previous 12 months were screened at 83 sites in Argentina, Brazil, Colombia, and Mexico. Statistical analysis was conducted between May and July 2025. Interventions: Patients were randomized to receive sacubitril/valsartan (target dose, 200 mg twice daily) or enalapril (target dose, 10 mg twice daily), in addition to standard therapy. Main Outcomes and Measures: The primary end point was a hierarchical composite outcome tested, in order, of death from cardiovascular causes, hospitalization for HF, or relative change in NT-proBNP from baseline to 12 weeks. The primary analysis was done using a win ratio approach. Results: Overall, 462 participants were randomized to receive sacubitril/valsartan and 460 to receive enalapril (mean [SD] age, 64.2 [10.8] years; 387 [42.0%] were female). Over a median (IQR) follow-up of 25.2 (18.4-33.2) months, cardiovascular death occurred in 110 patients (23.8% [18.3% wins in the hierarchical comparison]) in the sacubitril/valsartan group and 117 patients (25.4% [17.5% wins]) in the enalapril group. A total of 102 patients (22.1% [7.7% wins]) in the sacubitril/valsartan group and 111 (24.1% [6.9% wins]) in the enalapril group experienced a first hospitalization for HF. Patients in the sacubitril/valsartan group had a median (IQR) decrease in NT-proBNP of 30.6% (-54.3% to -0.9%) at 12 weeks, leading to 22.5% wins, while those in the enalapril group had a 5.5% (-31.9% to 37.5%) decrease (7.2% wins). The resulting stratified win ratio was 1.52 (95% CI, 1.28-1.82; P < .001) for sacubitril/valsartan compared with enalapril. Conclusions and Relevance: In patients with HF with reduced ejection fraction due to Chagas disease, there was no significant difference in clinical outcomes between sacubitril/valsartan and enalapril, but there was a greater reduction in NT-proBNP at 12 weeks in patients in the sacubitril/valsartan group.
