Transvenous electrical cardioversion of atrial fibrillation in horses: Horse and procedural factors correlated with success and recurrence.
Article in Journal of veterinary internal medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundTransvenous electrical cardioversion (TVEC) is 1 of the main treatment options for atrial fibrillation (AF) in horses. Large-scale studies on factors affecting success and prognosis have primarily been performed in Standardbred populations. HYPOTHESIS/
objectivesTo determine factors affecting cardioversion success, cardioversion difficulty and recurrence in a predominant Warmblood study sample. ANIMALS: TVEC records of 199 horses.
methodsRetrospective study of TVEC procedures of horses admitted for AF without severe echocardiographic abnormalities. Horse and procedural factors for success and cumulative amount of energy (≤ 600 J vs > 600 J) were determined using multivariable logistic regression. A survival analysis was performed to determine risk factors for recurrence.
resultsTwo hundred and thirty-one TVEC procedures were included, with a 94.4% success rate and 31.9% recurrence rate (51/160). Mitral regurgitation (OR 0.151, 95% CI 0.032-0.715, P = .02) and AF cycle length (OR 1.05, 95% CI 1.01-1.09, P = .02) were independent determinants for success. Catheter type (OR 0.154, 95% CI 0.074-0.322, P < .001), previous AF episode (OR 3.10, 95% CI 1.20-8.01, P = .02), tricuspid regurgitation (OR 2.54, 95% CI 1.25-5.13, P = .01), and body weight (OR 1.009, 95% CI 1.003-1.015, P = .004) were significantly correlated with cumulative amount of energy delivered. Significant risk factors for recurrence after a first AF episode were sex (stallion; HR 3.05, 95% CI 1.34-6.95, P = .008), mitral regurgitation (HR 1.91, 95% CI 1.08-3.38, P = .03), and AF duration (HR 1.001, 95% CI 1.0001-1.0026, P = .04). CONCLUSIONS AND CLINICAL IMPORTANCE: Both horse and procedural factors should be considered when assessing treatment options and prognosis in horses with AF.
