Predictor and prognostic modeling in cardiorenal syndrome type 2: a retrospective study of multicenter.
Article in Biomarkers in medicine, 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
backgroundType 2 CRS is characterized by the development of renal dysfunction secondary to chronic cardiac disease. Despite its high morbidity and mortality, there is a lack of robust diagnostic tools and prognostic models to guide clinical management.
methodsThis multicenter retrospective study included patients diagnosed with CRS type 2 based on the 2019 American Heart Association definition. Data were collected from electronic medical records of three hospitals between January 2021 and December 2023. Advanced statistical methods, including receiver operating characteristic (ROC) curve analysis, univariate Kaplan-Meier (KM) analysis, and multivariable Cox proportional hazards regression, were utilized to develop a nomogram for predicting patient prognosis.
resultsThe study included 519 patients with CRS-2. Independent predictors of adverse outcomes included elevated serum creatinine and blood urea nitrogen (BUN) levels, decreased platelet count, elevated B-type natriuretic peptide (BNP), and decreased oxygen partial pressure (PaO2). These findings suggest that close monitoring of these markers is essential in clinical practice to identify patients at high risk of adverse events early on.
conclusionOur study provides evidence that serum creatinine, BUN, platelet count, BNP, and PaO2 are independent predictors of adverse outcomes in patients with Type 2 CRS.
