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

Cumulative disability in neuromyelitis optica spectrum disorder (NMOSD) results from incomplete recovery following inflammatory, demyelinating attacks. Retrospective case studies and current clinical practice indicate that rapid treatment of acute attacks with apheresis limits injury and improves recovery. We evaluated the effects of apheresis and complement inhibition on lesion progression and recovery in a murine ex vivo cerebellar explant model of NMOSD injury. While both strategies reduced lesion formation relative to vehicle treatment, we observed that anti-C5 complement inhibition with eculizumab rapidly halted astrocyte destruction and immediately curtailed lesion extension; whereas an experimental mimic of immunoadsorption (IA), allowed for continued low level astrocyte destruction. During lesion recovery, C5 complement inhibition resulted in a faster rate of oligodendrocyte repopulation and improved myelin repair compared to IA. Complement inhibition may offer multiple benefits for the treatment of acute NMOSD attacks.
