A deep learning model integrating structured data and clinical text for predicting atrial fibrillation recurrence.
Article in NPJ digital medicine, 2026. 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
Multimodal perioperative data from patients undergoing atrial fibrillation (AF) ablation offer valuable insights for stratifying recurrence risk, yet remain underutilized in prediction models. This multicenter retrospective study included 2508 patients who underwent AF ablation at five Chinese centers: The Fourth Affiliated Hospital of Zhejiang University School of Medicine (Jan 2016-Mar 2024; Training Cohort), Taizhou Hospital of Zhejiang Province (Jan 2015-Jan 2024; Training Cohort), The Affiliated Hospital of Yunnan University (Jan 2016-Jan 2024; Validation Cohort), Jinhua People's Hospital (Jan 2020-Jan 2024; Test Cohort), and Ningbo Beilun Hospital (Jan 2020-Jan 2024; Test Cohort). We developed a dual-branch deep learning model to predict AF recurrence, in which structured data were processed via a 1D ResNet and textual data were encoded using four large language models (LLaMA-7B, Phi2-2.7B, Mistral-7B, and MedGemma-27B). The model incorporating MedGemma for text feature extraction performed best, achieving areas under the curve of 0.934 (95% CI: 0.921-0.946), 0.928 (95% CI: 0.904-0.950), and 0.911 (95% CI: 0.878-0.941) on the training, validation, and test sets, respectively. Our model integrates multimodal perioperative data from AF ablation patients, effectively identifies high-risk individuals, and may facilitate targeted interventions to reduce relapse.
