Construction and validation of a predictive model for the risk of atrial fibrillation in patients with heart failure with preserved ejection fraction: a single-center retrospective analysis.
Article in BMC cardiovascular disorders, 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
backgroundTo explore the risk factors for atrial fibrillation (AF) in patients with heart failure with preserved ejection fraction (HFpEF) and to construct a predictive model for AF in this population.
methodApproximately 334 patients with HFpEF who were treated in the Department of Cardiology at Fuyang People's Hospital from January 2022 to April 2024 were included. Patients were followed up for one year to observe whether they developed AF. All patients were randomly divided into a training set and a validation set in a 7:3 ratio, with the training set used for model construction and the validation set used for model performance evaluation. The Boruta algorithm was used for feature selection, and a predictive model was constructed using multivariate logistic regression analysis. Model performance was evaluated using the area under the receiver operating characteristic curve (AUC), Hosmer-Lemeshow goodness-of-fit test, calibration curve, and decision curve analysis (DCA).
resultsLogistic regression analysis revealed that coronary heart disease (CHD), body mass index (BMI), diastolic pressure (DP), free triiodothyronine (FT3), glomerular filtration rate (GFR), and sodium-glucose cotransporter 2 inhibitor (SGLT2i) were independent risk factors for the occurrence of atrial fibrillation in patients with heart failure with preserved ejection fraction (P < 0.05). The AUC was 0.871 in the training set and 0.825 in the validation set; the Hosmer-Lemeshow goodness-of-fit test yielded χ² = 5.3976 (P = 0.7144); decision curve analysis (DCA) indicated that the predictive model could provide superior clinical net benefit for patients with heart failure with preserved ejection fraction.
conclusionA predictive model constructed using six predictive variables-CHD, BMI, DP, FT3, GFR, and SGLT2i-can effectively predict the risk of atrial fibrillation in patients with HFpEF and aid in early risk stratification.
