Prognostic Value of Plasma Big Endothelin-1 in Patients Hospitalized for Heart Failure.
Article in Korean circulation journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
objectivesEndothelin-1 (ET-1) is a potent vasoconstrictor and multifunctional neuroendocrine hormone that is closely associated with the pathophysiology of heart failure (HF). Currently, the evidence about the predictive value of big ET-1 in HF remains insufficient. This study aims to investigate the prognostic importance of big ET-1 in HF.
methodsWe examined the incidence of cardiovascular death in a single-center retrospective cohort of HF (de novo, worsening, or chronic included).
resultsThe 4,368 hospitalized HF patients were enrolled. During the median follow-up of 875 (365-1,400) days, 851 (19.5%) patients had primary outcome events. Big ET-1 was independently associated with cardiovascular death as a continuous variable (hazard ratio [HR], 1.13; 95% confidence interval [CI], 1.06-1.21; p<0.001) and by tertiles (HR, 1.35; 95% CI, 1.06-1.72; p=0.017 for tertile 2 and HR, 1.70; 95% CI, 1.32-2.19; p<0.001 for tertile 3). This pattern of risk was maintained after further adjustment for NT-proBNP (HR, 1.11; 95% CI, 1.03-1.19; p=0.006 for continuous variable, HR, 1.30; 95% CI, 1.02-1.67; p=0.035 for tertile 2, and HR, 1.69; 95% CI, 1.23-2.05; p=0.034 for tertile 3). Net reclassification index (NRI) and integrated discrimination improvement (IDI) analysis showed that big ET-1 provided additional predictive power in combination with NT-proBNP (NRI, 0.11; 95% CI, 0.04-0.17; p=0.012 and IDI, 0.012; 95% CI, 0.003-0.017; p<0.001).
conclusionsElevated big ET-1 was independently associated with cardiovascular death in patients with HF. Big ET-1 may be a promising indicator of HF prognosis. In combination with NT-proBNP, big ET-1 may provide incremental predictive information.
