Revisiting the rhythm: A systematic review and meta-analysis of long-term arrhythmia outcomes after extracardiac versus intracardiac Fontan completion.

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
Studies on the arrhythmia incidence in the Fontan population, especially comparing intracardiac (IC) and extracardiac (EC) Fontan, are limited, with inconsistent findings. This meta-analysis aims to compare arrhythmia risk in EC and IC Fontan patients. Eligible studies comparing arrhythmia outcomes following different Fontan procedures, including EC conduit (ECC), lateral tunnel (LT), and classic Fontan, were identified through a systematic search of the PubMed, Cochrane Library, EMBASE, and Google Scholar databases from 2016 to 2025. Random-effects meta-analysis was performed to pool odds ratios (ORs). A subgroup analysis based on follow-up duration and a restricted analysis comparing ECC versus LT were conducted to explore heterogeneity. Twelve publications with 6280 patients were included in the final analysis. In our systematic review and meta-analysis, the EC Fontan was associated with significantly lower odds of arrhythmia compared to the IC Fontan (OR = 0.38, 95% confidence interval [CI]: 0.27-0.52,
