Diverticular Perforation with Normal C-reactive Protein in a Patient with Neuromyelitis Optica Spectrum Disorder Receiving Satralizumab.

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
Interleukin-6 blockade can blunt inflammatory biomarkers and mask serious infection. A 49-year-old woman with neuromyelitis optica spectrum disorder receiving satralizumab presented with mild abdominal pain; C-reactive protein levels were normal at the time of perforation despite a transient elevation early during hospitalization. Computed tomography revealed colonic diverticular perforation with a localized abscess. She improved with percutaneous drainage, targeted antimicrobials, and withdrawal of satralizumab, followed by transition to ravulizumab. This case suggests that satralizumab may obscure inflammatory responses, delaying recognition of gastrointestinal perforation. Normal C-reactive protein levels do not exclude complicated diverticulitis during interleukin-6 receptor blockade; early imaging and a low threshold for intervention are essential.
