Pharmacological Cardioversion With Antazoline in Atrial Fibrillation: The Results of the CANT Study.
Observational study in Journal of the American Heart Association, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 1 of them a synthesis that pooled 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.
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 Antazoline mesylate represents an antihistamine capable of rapid and safe cardioversion of atrial fibrillation, yet evidence concerning its efficacy in comparison to other medications is insufficient. The study aimed to evaluate the success rate and safety of pharmacological cardioversion of atrial fibrillation with intravenous antazoline ( CANT [Cardioversion With Antazoline Mesylate] study) in the setting of the emergency department. Methods and Results After reviewing 1984 medical records, 450 eligible patients (22.7%) with short-duration atrial fibrillation subject to pharmacological cardioversion were enrolled in a retrospective observational analysis. The choice of antiarrhythmic drug was left to the discretion of the attending physician. The primary end point was successful cardioversion in the emergency department. The safety end point comprised bradycardia <45 bpm, hypotension, syncope, or death. The study population (mean age, 65.5±11.9 years; 52.9% females) was characterized by a median atrial fibrillation episode duration of 10 hours. Antazoline, alone or in combination, was administered in 24.2% (n=109) and 40% (n=180), respectively; amiodarone was administered in 46.7% and propafenone in 9.3%, while ≥2 antiarrhythmic drugs were administered in 19.8% of patients. Antazoline had the highest success rate of pharmacological cardioversion among all drugs (85.3%), which was comparable with propafenone (78.6%; relative risk, 1.09, 95% confidence interval, 0.91-1.30; P=0.317) and higher than amiodarone treatment (66.7%; relative risk, 1.28, 95% confidence interval, 1.13-1.45; P<0.001; number needed to treat, 5.4). The rate of cardioversion with antazoline alone was higher than combined amiodarone and/or propafenone (68.1%; relative risk, 1.25; 95% confidence interval, 1.12-1.40, P=0.0001). No safety end points were reported in the antazoline group, while 5 incidents occurred in the non-antazoline cohort ( P=0.075). Conclusions Antazoline represents an efficacious and safe method of pharmacological cardioversion in a real-life setting.
