The risk of malnutrition as a predictor of arrhythmia recurrence after catheter ablation in patients with paroxysmal non-valvular atrial Fibrillation and heart failure with preserved ejection fraction.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundMalnutrition presents a significant challenge in managing patients with atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF), yet its impact on AF recurrence after catheter ablation in this population remains unclear.
methodsWe conducted a retrospective analysis of 204 patients with paroxysmal non-valvular AF and HFpEF who underwent radiofrequency or cryoballoon ablation. Risk of malnutrition as assessed using three screening tools: the Controlling Nutritional Status (CONUT) score, Prognostic Nutritional Index (PNI), and Nutritional Risk Index (NRI)]. We examined the relationship between risk of malnutrition and AF recurrence post-ablation.
resultsAfter a mean follow-up period of 11.2 ± 1.8 months, 43 patients (21.1%) experienced AF recurrence. Despite being classified as overweight or obese based on body mass index, many patients were at risk of malnutrition according to the CONUT score, NRI, and PNI. Adjusted analyses showed that higher CONUT scores (HR: 10.132; 95% CI: 2.545-40.336; P = 0.001), lower NRI (HR: 22.734; 95% CI: 6.399-80.776; P < 0.001), or lower PNI (HR: 9.469; 95% CI: 3.232-27.739; P < 0.001) were significantly associated with increased risk of AF recurrence. Restricted cubic spline regression revealed an inverted U-shaped relationship between the CONUT score and AF recurrence, and L-shaped relationships for both NRI and PNI with AF recurrence.
conclusionsSystematic nutritional assessment is crucial in patients with paroxysmal non-valvular AF and HFpEF. High CONUT scores, low NRI, or low PNI serve as independent predictors for AF recurrence. Further large-scale randomized controlled trials are required to validate these findings.
