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

Brain somatic mosaicism (BSM) refers to genome variation within brain cells that results from accumulated postzygotic mutations. These mutations can be used to understand cell lineage, molecular dynamics and disease processes. Unlike most other organs, brain cells are mostly fixed in position and not replaced throughout life. Thus, assessing mosaic variants (MVs) within the brain, including their spread and cell type-specific distributions and correlations with aging and cellular health, can reveal insights into neurodevelopmental, neuropsychiatric and neurodegenerative diseases. Extracting genetic material from human surgical brain resections, pregnancy remnants, or postmortem samples can reveal the origins of brain cells and uncover the effects of aging and disease on genomic integrity. Technological advances combining high-read-depth bulk sequencing, isolation of specific brain cell types, and single-cell multiomics can both detect and quantify MVs with good precision and recall. Research exploiting brain MVs is revolutionizing the understanding of the origins, mechanisms and potential treatments for brain conditions.
