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
Background: Acute pericarditis is a complication associated with radiofrequency or cryo-energy catheter ablation (CA) for arrhythmias and may be accompany pericardial effusion. A frequent complication of acute pericarditis is the onset of arrhythmias. While colchicine has demonstrated both anti-inflammatory and anti-arrhythmic effects in acute pericarditis, its efficacy in cases specifically developing post-CA remains unknown.The purpose of this study is to determine whether colchicine administration after the diagnosis of acute pericarditis due to CA is associated with a reduction in the recurrence rate of arrhythmias. Methods: Patients who developed acute pericarditis after CA for arrhythmias were retrospectively included in this study. Following the CA procedure, a group of patients was prescribed 0.5 mg of colchicine twice daily for 14 days at the operator's discretion, in addition to usual care. The primary outcome was freedom from arrhythmias within 12 months. Secondary outcomes included signs of pericarditis, recurrence of pericardial effusion, and the incidence of constrictive pericarditis. Results: Among the 75 consecutively enrolled patients, acute pericarditis occurred after: pulmonary vein isolation ( Conclusion: Colchicine, when added to usual care, doesn't appear associated with improved clinical outcomes in patients who developed acute pericarditis following CA for arrhythmias.Clinical trial number: UD5684993756.
