Toxic Effects of Excess Vitamins A, B6, and Folic Acid on the Nervous System.
Review in Behavioural neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
As one of the seven primary nutrients in the human body, vitamins are vital to maintaining good health. In recent years, there has been a completely new understanding of vitamins, and researchers have conducted more thorough investigations on them. These compounds, once viewed simply as supplemental nutrients, are now believed to play a more complex and critical role in human health. On the other hand, ingesting too much vitamins may cause negative health effects. Multiple studies have demonstrated a strong correlation between neurological problems and excessive vitamin intake. The purpose of this paper is to review the toxic effects of excessive vitamin intake on the nervous system, focusing on vitamin A and some of the B vitamins. It also analyzes the relationship between excessive vitamin intake and neurological dysfunction by reviewing the research findings in recent years, mainly including their possible mechanisms of action, clinical manifestations, and preventive measures, to provide ideas and inspiration for the subsequent clinical research.
