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
backgroundIdentifying slow conduction zones (SCZs) within the ventricular tachycardia (VT) substrate remains a major challenge in ischemic cardiomyopathy (ICM). We aimed to evaluate the role of coherent mapping (CM) in identifying SCZs within low-voltage areas (LVAs) in VT substrate mapping and assess its impact on VT ablation outcomes.
methodsThis retrospective study included 32 patients with ICM who underwent ablation for recurrent VT. CM-SCZs were compared with traditional substrate markers, including late potentials (LPs), local abnormal ventricular activities (LAVAs), and ILAM-based deceleration zones (DZs). Ablation strategies targeting CM-SCZs were analyzed in relation to procedural and clinical outcomes, including VT recurrence and total radiofrequency (RF) ablation time.
resultsCM-SCZs were consistently identified adjacent to LVAs in all cases, with a mean area of 5.2 ± 2.3 cm
conclusionCM improves the identification of SCZ within the VT substrate and enhances substrate-based ablation strategies. Incorporating CM-SCZs into VT ablation protocols may improve procedural success and reduce arrhythmia recurrence. Future studies should validate these findings and explore role of CM in broader patient populations.
