Review in CNS drugs, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04284059 (Adjuvant Effects of Vitamin A and Vitamin D Supplementation on Treatment of Children With ADHD), which is not on this map. Cited by 33 papers, 1 of them a synthesis that pooled it.

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.

Abstract

Vitamin A is an essential nutrient with important roles in immunological responses and in brain development. Its main metabolite is retinoic acid (RA), which is responsible for the neuroimmunological functions related to vitamin A. In the brain, RA is known to have interactions with other nuclear receptor-mediated signalling pathways. RA is involved in plasticity, regeneration, cognition and behaviour. In the peripheral blood, RA plays a major role both in increasing tolerance and in decreasing inflammation, through balancing T-lymphocyte populations. It is likely that RA synthesis may be manipulated by complex cross-talk among cells during infection and inflammation. The role of vitamin A in multiple sclerosis (MS) could be dual: at the same time as it decreases inflammation and increases tolerance of autoimmunity, it may also help in brain protection. The present review discusses the beneficial effects that vitamin A might have for controlling MS, although it must be clearly stated that, at the present time, there is no clear indication for using vitamin A as a treatment for MS. However, the results from the present review should encourage clinical trials with vitamin supplementation as a potential treatment or as an add-on option. Vitamin A acts in synergy with vitamin D, and the immunological homeostasis ensured by these vitamins should not be unbalanced in favour of only one of them.
