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

Oligodendrocyte loss in neurological disease leaves axons vulnerable to damage and degeneration, and activity-dependent myelination may represent an endogenous mechanism to improve remyelination following injury. Here we report that, while learning a forelimb reach task transiently suppresses oligodendrogenesis, it subsequently increases oligodendrocyte precursor cell differentiation, oligodendrocyte generation and myelin sheath remodeling in the forelimb motor cortex. Immediately following demyelination, neurons exhibit hyperexcitability, learning is impaired and behavioral intervention provides no benefit to remyelination. However, partial remyelination restores neuronal and behavioral function, allowing learning to enhance oligodendrogenesis, remyelination of denuded axons and the ability of surviving oligodendrocytes to generate new myelin sheaths. Previously considered controversial, we show that sheath generation by mature oligodendrocytes is not only possible but also increases myelin pattern preservation following demyelination, thus presenting a new target for therapeutic interventions. Together, our findings demonstrate that precisely timed motor learning improves recovery from demyelinating injury via enhanced remyelination from new and surviving oligodendrocytes.
