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

Multiple sclerosis (MS) is an autoimmune neuroinflammatory demyelinating disease of the central nervous system (CNS) that affects more than 2.5 million people worldwide. Remyelination represents a robust regenerative response to myelin damage; however, during the later stages of MS, this process largely fails. Upon demyelination, oligodendrocyte progenitor cells (OPCs) proliferate, migrate, and differentiate into mature remyelinating oligodendrocytes. Why does remyelination fail in MS? Platelets are small, oval, anucleate cells that circulate in the bloodstream and form a hemostatic plug to stop blood leakage upon endothelial damage. Platelet function is not restricted to hemostasis; they also display tissue-regenerative activities. Here, we review evidence suggesting that platelets act as modulators of OPC function during remyelination. Additionally, we describe platelet alterations associated with MS that may contribute to remyelination failure. Finally, we highlighted our previous study that addressed these issues. This study showed that in response to myelin damage, platelets transiently accumulate within the lesion. Interestingly, platelet depletion leads to a reduction in OPC differentiation, hindering remyelination. In vitro studies revealed that transient exposure to platelets boosts OPC differentiation, whereas sustained exposure to platelets suppresses this beneficial effect. Consistent with this observation, in an in vivo model of thrombocytosis (Calr
