Immune Checkpoint Inhibitor-Associated Hepatobiliary Toxicity: A Case of Concurrent Immune-Mediated Hepatitis and Acalculous Cholecystitis.
Article in ACG case reports journal, 2026. 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
Immune checkpoint inhibitors are associated with immune-related adverse events, including immune-mediated hepatitis, while acute acalculous cholecystitis remains exceedingly rare. We report a 52-year-old man with metastatic melanoma who developed concurrent grade 3 immune-mediated hepatitis and acute acalculous cholecystitis 2 weeks after combination ipilimumab-nivolumab therapy. He presented with right upper quadrant pain, jaundice, and marked transaminitis. Imaging showed gallbladder wall thickening with pericholecystic fluid without cholelithiasis, and alternative etiologies were excluded. The patient improved with conservative management without corticosteroids, with complete symptom resolution and biochemical normalization. This case highlights a rare dual hepatobiliary immune-related toxicity and the potential for conservative management in selected patients.
