Effects of volenrelaxin in worsening heart failure with preserved ejection fraction: a phase 2 randomized trial.
Trial report in Nature medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Relaxin is a peptide hormone that may decrease circulatory congestion and improve kidney function. In this study, we conducted a double-blind, international, multicenter trial to test whether volenrelaxin, a long-acting form of human relaxin, can improve left atrial (LA) function, reduce congestion and improve kidney function in patients with heart failure and preserved ejection fraction (HFpEF). We randomly assigned patients with New York Heart Association (NYHA) class II-IV HFpEF and recent heart failure (HF) decompensation to 25-mg, 50-mg or 100-mg volenrelaxin or placebo administered subcutaneously once weekly. The primary outcome was the change in LA reservoir strain at 26 weeks, with key secondary endpoints including changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP), estimated glomerular filtration rate (eGFR) and safety. The trial was stopped early by the sponsor because of evidence for worsening congestion after 332 participants had been enrolled (mean age 74 years, 49% women, mean body mass index 30.6 kg m
