Downregulation of serum Foxc2 in dilated cardiomyopathy: association with disease severity and cardiac function.
Article in Future science OA, 2025. 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
backgroundDilated cardiomyopathy (DCM) is one of the most frequent non-ischemic causes of heart failure. Foxc2 has been implicated in cardiovascular disease and angiogenesis, but its role in DCM remains undefined. This study aimed to compare serum Foxc2 levels in DCM and non-DCM patients and to assess its clinical relevance.
methodsIn this retrospective study, 92 patients (53 DCM, 39 non-DCM) were enrolled. Based on echocardiographic and clinical evaluations, patients were classified into non-DCM group (n = 39) and DCM group (n = 53). Serum Foxc2 concentrations were measured via ELISA, and correlations were analyzed with echocardiographic parameters and biomarkers (BNP, cTnI). ROC analysis assessed Foxc2's diagnostic performance, and Kaplan-Meier analysis evaluated 2-year MACE risk.
resultsSerum Foxc2 levels were significantly lower in the DCM group (35.33 ± 27.99 μg/mL vs. 77.51 ± 28.94 μg/mL), and correlated with cardiac function (positive: LVEF, LVFS; negative: LVEDd, BNP, cTnI). ROC analysis demonstrated high diagnostic accuracy for Foxc2 (AUC 0.862). Patients with Foxc2 levels≥ 33.945 μg/mL showed a reduction in 2-year MACE risk (HR 0.187) compared to those with levels below the threshold.
conclusionFoxc2 may serve as a promising biomarker for DCM diagnosis and prognosis, supporting for further mechanistic investigations.
