The Cardio-Biliary Reflex in Gallbladder Disease: A Case Report and Literature Review.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This case report describes an elderly female presenting with simultaneous biliary colic and symptomatic sinus bradycardia. The resolution of her bradycardia with pain management alone suggested Cope's sign, or the cardio-biliary reflex (CBR), as the underlying cause. This reflex is a well-recognized physiological response in which gallbladder pathology triggers vagal nerve signals, potentially causing significant alterations in cardiac rhythm and often mimicking primary heart conditions. This case illustrates that even uncomplicated biliary colic can induce this effect and emphasizes the importance for clinicians to consider this reflex in the differential diagnosis of bradyarrhythmia accompanied by abdominal pain. Recognizing CBR is crucial for directing management toward the correct biliary pathology and avoiding unnecessary cardiac investigations or interventions.
