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.

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.

Abstract

Patients with neuromyelitis optica spectrum disorder (NMOSD) may experience increased signs and symptoms of their underlying disease when vaccinated against meningococcal disease before receiving complement component 5 inhibitor therapies. This retrospective analysis indicated an overall low relapse incidence (mean [range], 3.3% [0.7%-10.6%]) of physician-reported relapses occurring within 4 weeks of meningococcal vaccination in those screened in CHAMPION-NMOSD (NCT04201262), randomized to eculizumab or placebo in PREVENT (NCT01892345), and from the Japanese postmarketing surveillance of eculizumab in patients with anti-aquaporin-4 antibody-positive NMOSD. Further studies are needed to determine if postvaccination relapses are attributable to vaccination or inherent relapse risk among these patients.
