Insulin resistance, left atrial anatomical remodeling, and recurrence in patients with atrial fibrillation undergoing radiofrequency ablation.
Article in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundInsulin resistance (IR) is associated with both the anatomical remodeling of the left atrium and the pathogenesis of atrial fibrillation (AF). However, the exact extent of this correlation and its influence on AF recurrence in individuals undergoing radiofrequency catheter ablation (RFCA) remains unclear.
methodsA total of 910 patients with AF who underwent RFCA were included in this analysis. IR was evaluated using the triglyceride glucose-body mass index (TyG-BMI), while the left atrium's enlargement was assessed using the left atrium anteroposterior dimension (LAD). The association between TyG-BMI and LAD with AF recurrence was examined through the Kaplan-Meier method, restricted cubic splines (RCS), and adjusted Cox regression. Receiver operating characteristic curve (ROC) analysis was conducted to evaluate the predictive capabilities of TyG-BMI and LAD for outcomes. Additionally, mediation analysis was utilized to explore the indirect impact of TyG-BMI on AF recurrence mediated through LAD.
resultsOver a median 12-month follow-up period, 189 (20.77%) cases of AF recurrence were observed. The likelihood of AF recurrence rose with elevated TyG-BMI and LAD levels. After adjusting for multiple factors, both TyG-BMI and LAD were significant predictors of AF recurrence. Subgroup and interaction analyses reaffirmed the consistency of the main findings. Both TyG-BMI (non-linear, P = 0.302) and LAD (non-linear, P = 0.001) demonstrated a positive dose-response relationship with AF recurrence, as depicted by the RCS curves. The areas under the ROC curves for TyG-BMI and LAD in predicting AF recurrence were 0.634 and 0.639, respectively. Notably, LAD partly mediated the association between TyG-BMI and AF recurrence, accounting for an 19.23% proportion.
conclusionThe anatomical remodeling of the LA partially mediated the relationship between IR and AF recurrence. Ameliorating IR may serve as a potential upstream therapy for the comprehensive management of AF.
