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

introductionDementia is a public health challenge and exposures likely contribute to risk, though many have not been evaluated. We screened chemicals for enrichment with dementia genes and related pathways.

methodsWe obtained gene lists from Agora and the Comparative Toxicogenomics Database (CTD) for 1008 chemicals and nine dementia-related pathways (e.g., Alzheimer's disease, tauopathies). We tested pairwise chemical-dementia gene enrichment using Fisher exact tests and proportional reporting ratios (PRRs), accounting for multiple comparisons with false discovery rate (FDR < 1 × 10

resultsOf the chemicals tested, 817 (81.1%) were enriched for at least one dementia pathway and 71 with all nine pathways, including benzo(a)pyrene, ethanol, paraquat, and particulate matter. We observed 295 chemicals enriched for Alzheimer's disease, including sodium arsenite (PRR = 57.9) and 305 enriched for tauopathies, including bisphenol A (PRR = 37.7). DISCUSSION: We identified chemicals enriched for dementia pathways, suggesting broad classes of chemicals contribute to dementia.
