1 · What the graph read from 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.

2 · The registry

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 (ICIs) are known to induce gastrointestinal adverse events. Colitis occurs most frequently, and gastritis is less common. A few case reports of gastritis induced by ICIs have indicated that colitis induced by cytotoxic T-lymphocyte antigen-4 (CTLA-4) resembles inflammatory bowel disease (IBD) and that programmed death-1/programmed death ligand-1 (PD-1/PD-L1) inhibitor can also induce the same type of colitis. We herein encountered a case of gastritis arising after 25 cycles of pembrolizumab administration in which the pathological and endoscopic findings resembled those of IBD. ICIs may induce gastritis in a manner similar to the pathogenesis of IBD.
