Left Atrial Volume Index and Left Ventricular Mass Index Determine the Benefits of Spironolactone in Patients With Heart Failure With Preserved Ejection Fraction.
Trial report in Journal of the American Heart Association, 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
backgroundIt is unclear whether patients with heart failure with preserved ejection fraction respond to spironolactone based on cardiac structure or function.
methodsA post hoc analysis was performed among participants with left ventricular (LV) ejection fraction ≥50% and evidence of abnormal LV diastolic function or filling pressures in TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist Trial). Log-rank tests and Cox regression models were used for comparison between groups.
resultsTotally, 757 subjects were qualified and stratified by parameters on cardiac structure or function. In patients with increased left atrial volume index, spironolactone reduced cardiovascular mortality (adjusted hazard ratio [HR], 0.48 [95% CI, 0.24-0.98];
conclusionsSpironolactone reduced cardiovascular mortality, heart failure hospitalization, or the composite outcome of cardiovascular mortality, heart failure hospitalization, and aborted sudden death in patients with heart failure with preserved ejection fraction with increased left atrial volume index or LV mass index.
