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

How does the brain build and maintain the precise wiring patterns that distinguish one neuron from another? Clustered protocadherins (PCDHs)-a family of cell-surface molecules that give each neuron a unique identity tag-are central to this process. Their expression is famously controlled by an elaborate locus-specific epigenetic system involving DNA methylation, CTCF binding, and chromatin looping. Whether the activity of the broader epigenetic regulatory machinery is coordinated with protocadherin expression across the human brain has not been systematically tested. Here we show that epigenetic regulators are preferentially co-expressed with protocadherins across multiple human brain regions, suggesting a broader transcriptional coordination than the locus-specific mechanisms previously characterized. Using GTEx v8 RNA-seq data from 2,642 brain samples across 13 regions, we conducted a genome-wide co-expression screen and observed a 6.5-fold enrichment of epigenetic regulators in the top 5% of PCDH-coordinated genes in prefrontal cortex (Fisher's exact p = 2.8 × 10
