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

1,25-Dihydroxyvitamin D3 (1,25(OH)2D3) has recently been found to suppress experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS). Although its effect was attributed to an anti-inflammatory mechanism, it is not clear whether this treatment can also directly act on neural cells to promote CNS recovery. The present study investigates the effect of various concentrations of 1,25(OH)2D3 on neural stem cell (NSC) proliferation and their differentiation to oligodendrocytes, the myelinating cells. We have, for the first time, shown that NSCs constitutively express vitamin D receptor (VDR), which can be upregulated by 1,25(OH)2D3. This vitamin significantly enhanced proliferation of NSCs, and enhanced their differentiation into neurons and oligodendrocytes, but not astrocytes. NSCs treated with 1,25(OH)2D3 showed increased expression of NT-3, BDNF, GDNF and CNTF, important neurotrophic factors for neural cell survival and differentiation. Overall, we demonstrated that 1,25(OH)2D3 has a direct effect on NSC proliferation, survival, and neuron/oligodendrocyte differentiation, thus representing a novel mechanism underlying its remyelinating and neuroprotective effect in MS/EAE therapy.
