Systematic Review: Mineralocorticoid Receptor Antagonists in Heart Failure with Preserved and Mildly Reduced Ejection Fraction.
Synthesis in Arquivos brasileiros de cardiologia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Heart failure with preserved ejection fraction (HFpEF) or mildly reduced ejection fraction (HFmrEF) is a prevalent condition associated with significant morbidity and mortality, and the benefits of mineralocorticoid receptor antagonists (MRAs) remain unclear. To develop a systematic review on the use of MRAs in patients with HFpEF or HFmrEF, a systematic review and meta-analysis were conducted using a broad search strategy in the following databases: MEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL). Randomized controlled trials that evaluated the use of MRAs in patients with HFpEF compared to control groups were included. The quality of evidence and the strength of the recommendation were assessed according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. Eight studies were included. No statistically significant differences were observed for the outcomes of overall mortality and cardiovascular mortality compared to the control group for any of the MRAs. A benefit was observed with a reduced risk of hospitalization for heart failure (relative risk: 0.87; 95% confidence interval: 0.79 to 0.96; moderate certainty of evidence) and of worsening heart failure events (relative risk: 0.83; 95% confidence interval: 0.77 to 0.89; high certainty of evidence). The results of the meta-analysis indicate a significant benefit from MRAs, spironolactone or finerenone, to reduce hospitalizations and worsening heart failure events in patients with HFpEF or HFmrEF.
