1 · What the graph read from it

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.

2 · The registry

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

Background: Pulmonary vein isolation (PVI) with cryoballoon technology is widely used for rhythm control in atrial fibrillation (AF). However, there are limited data on its effectiveness in patients with the left common pulmonary vein (LCPV) variant. Objective: The study aimed to examine the outcomes of cryoballoon ablation in patients with the LCPV variant. Methods: The Israeli Catheter Ablation Registry is a prospective, multicenter cohort that included citizens who underwent PVI during the years 2019-2021. Study endpoints were acute isolation success of the pulmonary veins (PVs), AF recurrence, and the need for a repeat ablation procedure at 12 months. Results: The study included 74 patients with the LCPV variant and 822 patients with standard PV anatomy. The acute isolation success rate of the LPVs was significantly lower in LCPV variant patients compared with those with a standard anatomy. However, there was no significant difference in the acute isolation success rate of the right PVs between the 2 groups. At 12 months, the rates of AF recurrence did not differ significantly between the LCPV variant group (17.6%) and the standard anatomy group (11.1%) ( Conclusion: In our study, we found that isolating the LCPV using cryoballoon PVI was more challenging than isolating standard anatomy. Despite this, the effectiveness of cryoballoon ablation in patients with LCPV anatomy did not differ significantly from that in the standard anatomy group.
