Does Disopyramide Still Have a Place in the Management of Obstructive Hypertrophic Cardiomyopathy?
Review in CJC open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Hypertrophic cardiomyopathy (HCM) is a relatively common inherited cardiac disorder associated with a left ventricular hypertrophy that cannot be explained by another cardiac or systemic disorder. One of the core pathophysiology features is left ventricular outflow tract obstruction (obstructive HCM [oHCM]), and this pathology could lead to complications, including sudden cardiac death and heart failure. Current treatment strategies for symptomatic oHCM consist of historical pharmacologic agents that are often based on nonrandomized, limited data or expert opinion. This article presents a critical appraisal of disopyramide, one of the pharmacologic options available in Canada for managing oHCM. The author concludes that robust clinical evidence supporting the use of disopyramide in treating oHCM is lacking, and that disopyramide should be reserved as a last resort for nonresponders to pharmacologic treatment and for those in whom invasive therapies are not indicated.
