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
objectiveAtrial fibrillation (AF), the most common cardiac rhythm disorder, affects approximately 2% of the general population and is associated with increased risk of stroke and mortality as well as reduced exercise capacity and quality of life. After restoring normal sinus rhythm, a portion of these patients develops recurrent AF despite optimal medical treatment. In this study, we aimed to assess the relationship between the presence of fragmented QRS (fQRS) and AF recurrence following successful electrical cardioversion (ECV). MATERIAL AND
methodsA total of 306 patients with nonvalvular persistent AF achieving restoration of the sinus rhythm after successful ECV were included in this study. After ECV, patients were monitored at least 6 months for recurrence. The patients were divided into two groups according to the presence of fQRS and compared for AF recurrence during follow-up.
resultsPatients were followed up for a mean time of 220 ± 113 days. AF recurred in 119 patients, corresponding to a recurrence rate of 38.8%. AF recurrence was found to be significantly increased in patients with fQRS as compared to those without fQRS (76.4% vs. 23.5%, p < .001). Furthermore, the presence of fQRS was higher in patients with recurrent AF as compared to others (57.1% vs. 11.2%, p < .001). In multiple regression analyses, the presence of fQRS was one of the independent predictors of AF recurrence (hazard ratio: 9.670, 95% CI: 4.714-19.837, p < .001).
conclusionThe presence of fQRS may be associated with the recurrence of AF after successful ECV in persistent nonvalvular AF patients.
