Clinical risk prediction models for worsening heart failure events and all-cause mortality in adults with mild-to-moderate chronic kidney disease.
Article in ESC heart failure, 2026. 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
introductionTo develop and internally validate electronic health record (EHR)-based machine-learning models to predict worsening heart failure (WHF) events across care settings and all-cause mortality among adults with mild-to-moderate chronic kidney disease (CKD).
methodsWe studied adults with mild-to-moderate CKD [estimated glomerular filtration rate (eGFR) 30-59 ml/min/1.73 m² or eGFR ≥60 with albuminuria] receiving care in a large health system from 2012 to 2021; outcomes were ascertained through 31 December 2022. Primary outcomes were (i) WHF events-outpatient encounters, emergency department (ED)/observation stays, and hospitalizations-identified using a validated natural language processing algorithm, and (ii) all-cause mortality. Models [extreme gradient boosting (XGBoost)] used an 80:20 train-test split and >500 EHR-derived covariates. Discrimination [area under the curve (AUC)] and calibration (slope) were evaluated overall and across subgroups by age, sex, race and ethnicity, and CKD stage.
resultsAmong 375 495 adults (mean age 64 ± 16 years; 54% women; 53% non-Hispanic White; mean eGFR 76 ± 26 ml/min/1.73 m²), the WHF model achieved AUC 0.887 (95% CI 0.879-0.893) with calibration slope 0.955; the mortality model achieved AUC 0.875 (95% CI 0.868-0.883) with calibration slope 0.914 in the test set. Performance was consistent across age, sex, and race and ethnicity, with a slight decrement as CKD stage worsened.
conclusionsElectronic health record-based machine-learning models accurately predicted WHF and mortality in mild-to-moderate CKD with strong calibration across key subgroups. These models are positioned for EHR deployment to support risk-stratified cardiovascular-kidney-metabolic care-prioritizing guideline-directed therapies and care pathways for those at highest risk.
