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
purposeCatheter radiofrequency ablation (RFA) is an effective treatment for symptomatic paroxysmal atrial fibrillation (AF). It has been demonstrated that the multielectrode pulmonary vein ablation catheter (PVAC) has favourable outcomes at 6-12 months post-ablation, but there are only few studies with a long-term follow-up.
methodsWe retrospectively reviewed 77 consecutive PVAC procedures in our centre, from November 2007 to December 2012. RFA was attempted in patients with symptomatic paroxysmal AF (mean age 58.7 ± 9.8 years, 50 men (64.9 %). The ablation strategy consisted of circumferential pulmonary vein isolation (CPVI) with the PVAC system. A questionnaire was used over the follow-up period to assess the efficacy of AF ablation. Success was defined as freedom from AF/atrial flutter or atrial arrhythmia for a period ranging from 3 to 12 months or more.
resultsSeventy-seven patients were included with paroxysmal AF. The mean duration of the procedure was 99.6 ± 26 min and fluoroscopy time 19.4 ± 6.8 min. Time of RFA was 22.4 ± 5.8 min. Acute complication rate was 10.4 % (the most frequent was vascular injury for 6 patients 7.8 %, 1 patient presented sepsis (1.3 %), 1 patient presented transient ischemic stroke). After a single procedure at a mean FU of 55 ± 11 months, 54/77 (70.1 %) patients were free of symptomatic AF.
conclusionsThese long-term results suggest that PVAC is an efficient system for CPVI of symptomatic paroxysmal AF.
