Ketamine-Induced Cholangiopathy With Concomitant Hemorrhagic Cystitis: An Emerging and Underrecognized Cause of Cholestasis.
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
Ketamine-induced cholangiopathy (KIC) is a rare but increasingly recognized manifestation of chronic ketamine toxicity, often accompanied by urinary tract injury such as hemorrhagic cystitis. We report the case of a 55-year-old female with recurrent hemorrhagic cystitis and a long-standing history of intermittent recreational ketamine use who presented with asymptomatic cholestatic liver enzyme abnormalities. Hepatobiliary ultrasound revealed hepatic steatosis without ductal dilatation, and magnetic resonance cholangiopancreatography demonstrated multifocal biliary stricturing with a beaded appearance of the intrahepatic bile ducts. Serological testing for autoimmune and infectious etiologies was negative. Cystoscopy revealed inflammatory bladder changes, and histopathology confirmed ketamine-induced hemorrhagic cystitis. Following cessation of ketamine use, the patient demonstrated biochemical improvement. This case emphasizes the multisystem toxic potential of ketamine, highlighting the importance of recognizing KIC with concomitant hemorrhagic cystitis as an emerging cause of cholestasis and urinary tract injury.
