Concomitant Use of Diltiazem With Direct Oral Anticoagulants and Bleeding Risk in Atrial Fibrillation.
Article in Journal of the American Heart Association, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 2 of them syntheses 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 Diltiazem, a moderate cytochrome P450 3A4 isozyme/P-glycoprotein inhibitor, may potentiate the bleeding risk of direct oral anticoagulants (DOACs) through pharmacokinetic interactions. We evaluated the association between concomitant use of diltiazem with DOACs and bleeding among patients with atrial fibrillation, across varying degrees of kidney function. Methods and Results We identified 4544 patients with atrial fibrillation who were initiated on rivaroxaban (n=1583), apixaban (n=2373), or dabigatran (n=588), between 2010 and 2019 in Geisinger Health, with a mean age of 72 years and an estimated glomerular filtration rate of 70 mL/min per 1.73 m
