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.

Abstract
introductionPosterior wall isolation (PWI) added to pulmonary vein isolation (PVI) is increasingly used despite limited evidence of clinical benefit. We investigated the feasibility, durability, and efficacy of index-procedure PVI + PWI radio frequency ablation (RFA) in patients with persistent atrial fibrillation (PeAF). METHODS AND
resultsTwenty-four patients with PeAF participated in the prospective PeAF-Box study and underwent RFA with wide area circumferential ablation, roof- and inferior lines to achieve PVI + PWI at index procedure. Follow-up included monitoring by an implantable cardiac monitor, esophagoscopy and mandated invasive lesion-reassessment at 6 months. PWI was achieved at minor procedural cost in all patients following PVI. In 33% of patients a median of three ablations in the narrow zone between the center of the posterior wall (PW) and the posterior right carina was pivotal for swift achievement of PWI. At the 6-month reassessment procedure 85% (95% confidence interval [CI]: 77%-92%) of pulmonary veins (PVs) and 46% (95% CI: 26%-67%) of PWs remained durably isolated. AF recurred in 25% and was associated with PV-reconnection (p = .02) but not PW-reconnection (p = .27). AF-burden was 0% (interquartile range [IQR]: 0%-0%) overall and after recurrence 1% (IQR: 0%-7%).
conclusionIndex procedure PVI + PWI for PeAF was feasible when recognizing that limited ablation in a PW center-to-right-carina zone was required in a subset of patients. Despite limited chronic PWI durability this strategy was followed by low AF-burden. A PVI + PWI strategy appears promising in ablation for PeAF.
