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
Acute heart failure (AHF) is a leading cause of hospitalization and mortality worldwide. Despite advances in biomarker-based evaluation, accurate diagnostic and prognostic stratification remains challenging in everyday clinical practice. Growth differentiation factor-15 (GDF-15) has emerged as a biomarker associated with advanced disease profiles, poor outcomes and complex underlying pathophysiological processes in heart failure (HF). This study aimed to investigate the diagnostic and prognostic value of GDF-15 in the acute setting and to evaluate its incremental role within multimarker assessment strategies. In this prospective cohort study, 60 patients hospitalized with AHF and 42 control subjects were enrolled. Circulating levels of GDF-15, N-terminal pro-B-type natriuretic peptide (NT-proBNP), and high-sensitivity cardiac troponin I (hs-cTnI) were measured at admission. Diagnostic performance was assessed using receiver operating characteristic (ROC) analysis and multivariable logistic regression. Prognostic value was evaluated for in-hospital, short-term, and one-year mortality, including multimarker models. GDF-15 levels were significantly elevated in AHF and demonstrated a favorable diagnostic profile, with high specificity and acceptable sensitivity. When integrated into multivariable diagnostic models, GDF-15 added significant value beyond established cardiac biomarkers. For prognosis, standalone biomarkers showed limited long-term discrimination, whereas multimarker approaches incorporating GDF-15 improved short-term mortality prediction and enhanced one-year risk stratification in patients with markedly elevated NT-proBNP levels. GDF-15 provides independent diagnostic and prognostic information in AHF and enhances multimarker strategies for comprehensive patient assessment, supporting its integration as a complementary biomarker in contemporary AHF evaluation.
