Genetic determinants of low vitamin B12 levels in Alzheimer's disease risk.
Article in Alzheimer's & dementia (Amsterdam, Netherlands), 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionThere is observational evidence that low circulating levels of vitamin B12 are associated with an increased risk of Alzheimer's disease.
methodsWe used a two-sample summary-statistics-based Mendelian randomization design to assess the relationship of genetic factors contributing to vitamin B12 with late-onset Alzheimer's disease risk.
resultsOur results do not support a causal role of decreased vitamin B12 levels on Alzheimer's disease risk. DISCUSSION: This work encourages research on other modifiable biomarkers for Alzheimer's disease risk.
