Histone acetylation maps in aged mice developmentally exposed to lead: epigenetic drift and Alzheimer-related genes.
Article in Epigenomics, 2018. 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
aimEarly life exposure to lead (Pb) has been shown to increase late life biomarkers involved in Alzheimer's disease (AD) pathology. Here, we tested the hypothesis that latent over expression of AD-related genes may be regulated through histone activation pathways.
methodsChromatin immunoprecipitation sequencing was used to map the histone activation mark (H3K9Ac) to the mouse genome in developmentally Pb exposed mice on postnatal days 20, 270 and 700.
resultsExposure to Pb resulted in a global downregulation of H3K9Ac across the lifespan; except in genes associated with the Alzheimer pathway. DISCUSSION: Early life exposure to Pb results in an epigenetic drift in H3K9Ac consistent with latent global gene repression. Alzheimer-related genes do not follow this trend.
