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

backgroundNeuromyelitis optica spectrum disorder (NMOSD) is a severely disabling autoimmune disease that predominantly impacts the optic nerves and spinal cord. It is often linked to immunoglobulin G (IgG) antibodies targeting the aquaporin-4 water channel (AQP4-IgG). Rituximab, which depletes CD20-positive B cells, is effective in reducing the frequency of NMOSD relapses. The objective of this retrospective, 5-year observational study was to evaluate the effectiveness and safety of rituximab in patients with AQP4-IgG-positive NMOSD.

methodsWe conducted a multicenter, retrospective study using prospectively collected data from 23 multiple sclerosis (MS) and NMOSD centers (22 in Italy, 1 in Switzerland). The study cohort included patients with AQP4-IgG-positive NMOSD who had completed rituximab induction therapy, with data collected up to May 2024. Two maintenance strategies were used-fixed 6-monthly infusions or reinfusions guided by flow cytometry-on the basis of CD19

resultsA total of 138 patients were analyzed. ARR significantly decreased from 1.54 (95% confidence interval (CI) 1.34-1.75) before rituximab to 0.15 (95% CI 0.12-0.19) over the 5-year follow-up. Approximately 33% of patients experienced at least one relapse during treatment, after a median time of 5.21 months. Higher pre-rituximab relapse rates were associated with shorter TTFR. Subtle increases of 0.5-1 points in EDSS between relapses were observed in one third of patients. Mild infections were common, and 21% of patients experienced infusion-related reactions. In addition, six patients developed malignancies.

conclusionsOver 5 years, rituximab consistently reduced the incidence of relapses in patients with NMOSD, though 33% of them still experienced a relapse during this period, generally within the first 6 months of treatment. No unexpected adverse events were identified. While safety monitoring remains crucial, further studies are needed to better understand rituximab's impact on NMOSD management.
