Immune checkpoint inhibitor-induced anti-Hu antibody-associated gastrointestinal pseudo-obstruction: a case report and literature review.
Review in Frontiers in immunology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The immune checkpoint inhibitors (ICIs)-induced anti-Hu antibody-associated gastrointestinal pseudo-obstruction (GIPO) is a paraneoplastic neurological syndrome related to autoantibodies. It has a very low incidence but a high mortality rate. This report presents the case of a patient with extensive-stage small-cell lung cancer who developed recurrent bowel obstruction symptoms following ICI therapy. Colonoscopy and abdominal CT tomography failed to identify the underlying cause. A definitive diagnosis of GIPO was made based on the histological findings from an exploratory laparotomy and serum levels of paraneoplastic antibodies. Despite treatment with corticosteroids, no significant improvement was detected in the symptoms, and the patient ultimately died. This case highlights the challenges of managing this rare complication. When unexplained bowel obstruction occurs during ICI therapy, antineuronal antibody testing should be performed to exclude GIPO, as early identification and intervention can reduce mortality.
