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
objectivesThe short-term results of video-assisted thoracoscopic surgical ablation (VTSA) with box lesion have been highly variable, and the actual efficacy requires clarification through longer follow-ups. We aimed to report which patients might benefit more from VTSA with box lesion by longer follow-up.
methodsFrom September 2010 to November 2016, patients with atrial fibrillation (AF) who underwent VTSA with box lesion were screened. All enrolled patients visited the outpatient clinic and underwent 24-h Holter monitoring at 3, 6 and 12 months after surgery and annually thereafter.
resultsA total of 91 consecutive patients [age, 58.0 (interquartile interval from 52.0 to 62.0) years; male, 71.4%] with paroxysmal (67%) or persistent/long-standing persistent (33%) AF were enrolled. After a median follow-up of 48 months (interquartile interval from 36 to 60 months), freedom from atrial tachyarrhythmias without antiarrhythmic drugs (AADs) was 76.5%, 66.0% and 66.0% for paroxysmal AF and 58.6%, 47.8% and 34.2% for persistent/long-standing persistent AF at 12, 36 and 60 months, respectively (P = 0.017). The preoperative left atrial diameter >40 mm (hazard ratio: 2.837, 95% confidence interval: 1.408-5.716; P = 0.004) and age >50 years (hazard ratio: 2.927, 95% confidence interval: 1.359-6.305; P = 0.006) were associated with recurrences of atrial tachyarrhythmias. In patients with paroxysmal AF and left atrial diameter ≤40 mm (n = 43), freedom from atrial tachyarrhythmias without AADs was 81.4%, 74.3% and 74.3% at 12, 36 and 60 months, respectively.
conclusionsIn patients with paroxysmal AF and left atrial diameter ≤40 mm, 5-year freedom from atrial tachyarrhythmias without AADs was 74.3%, which was better than that in patients with left atrial diameter >40 mm. A larger sample size and improved study design are needed to confirm our conclusions.
