The Predictive Value of Real-World Cardiologist Performance (RWCP) Score in Atrial Fibrillation Recurrence Risk After Radiofrequency Ablation.
Article in Journal of cardiovascular electrophysiology, 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
objectiveTo explore the predictive value of Real-world Cardiologist Performance (RWCP) score for atrial fibrillation (AF) recurrence risk after radiofrequency catheter ablation (RFCA).
methodsPatients with nonvalvular AF who underwent first-time RFCA at Luoyang Central Hospital affiliated to Zhengzhou University between October 2021 and June 2023 were included in this study. Detailed ablation data were exported from CARTO®3 system (Biosense Webster, USA), based on which, four parameters, including discharge time proportion, Catheter Contact Force Stability (C3-FOT proportion), Ablation Index Consistency (SURPOINT/TOP-4 proportion) and fragmented points proportion, were calculated. Then, the RWCP score was calculated from these parameters for each patient. Predictive value of the RWCP score for AF recurrence risk were assessed using Cox regression and Kaplan-Meier analyses.
resultsA total of 148 AF patients were enrolled, including 68 males and 80 females. During follow-up, 30 patients (20.3%) experienced AF recurrence. The RWCP score was calculated using Cox regression coefficients: RWCP score = (left ring discharge time ratio × 2.853) - (left C3-FOT proportion × 0.91) + (left SURPOINT/TOP4 × 2.943) + (left fragmented points proportion × 0.423) - (right ring discharge time ratio × 4.039) - (right C3-FOT proportion × 6.159) - (right SURPOINT/TOP4 × 1.312) - (right points fragmented proportion × 4.425). It was found that patients with higher RWCP scores (-12.53 to 5.79) had higher recurrence risk than those with low scores (-28.68 to -12.76) (HR = 5.55, 95% CI: 2.23-13.80, p = 0.0002). Kaplan-Meier analysis confirmed this (p
conclusionThe RWCP score shows promise as a tool for evaluating ablation completeness, assessing cardiologist performance and predicting AF recurrence risk after ablation.
