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

Neurodegeneration occurring in multiple sclerosis (MS) contributes to the progression of disability. It is therefore important to identify and neutralize the mechanisms that promote neurodegeneration in MS. Here, we report that oxidized phosphatidylcholines (OxPCs) found in MS lesions, previously identified as end-product markers of oxidative stress, are potent drivers of neurodegeneration. Cultured neurons and oligodendrocytes were killed by OxPCs, and this was ameliorated by microglia. After OxPC injection, mouse spinal cords developed focal demyelinating lesions with prominent axonal loss. The depletion of microglia that accumulated in OxPC lesions exacerbated neurodegeneration. Single-cell RNA sequencing of lesioned spinal cords identified unique subsets of TREM2
