Evaluation of Urolithin A Efficacy in Heart Failure Patients with Reduced Ejection Fraction: A Randomized, Double-blind, Crossover, Placebo-controlled Clinical Trial.
Trial report in Reviews on recent clinical trials, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundMitochondrial dysfunction and impaired mitophagy are integral to myocyte loss and the progression of heart failure. Urolithin A (UA), a microbiota-produced metabolite of ellagitannins and ellagic acid, is a known stimulator of mitophagy and mitochondrial biogenesis that has shown cardioprotective effects in experimental models.
methodsA randomized, double-blind, placebo-controlled 2×2 crossover trial was conducted on 10 patients with HF with reduced ejection fraction (HFrEF). The trial design involved two 4- week intervention periods of UA (500 mg BID) and placebo, separated by a 2-week washout phase. The patients underwent two-dimensional echocardiogram examination as well as blood sampling at the beginning and end of each period.
resultsAll patients completed the study. The results failed to reveal any significant effect of UA supplementation on echocardiographic measures (LVEF, LVEDD, LVESV, and TAPSE). Plasma concentrations of pro-BNP, glucose, and CRP (p >0.05) were also not altered. Serum HDL-C levels were increased with UA compared with placebo (+6.46 ± 2.33 mg/dL, p =0.026), whereas other lipid indices (LDL-C, triglycerides, total cholesterol, and VLDL-C) remained unchanged (p >0.05).
conclusionThe results of the present study do not support any positive effect of UA supplementation in improving echocardiographic and biochemical indices of HFrEF. Further studies with higher doses of UA and longer supplementation duration are encouraged to be conducted.
