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

Ageing has profound effects on the human brain across the lifespan. Cognitive testing and brain imaging are currently used to monitor healthy and pathological brain ageing. However, peripheral markers of cognitive function, cognitive ageing and neurological disease could provide a valuable, minimally invasive approach to tracking these processes longitudinally. In this Review, we introduce the concept of DNA methylation-based biomarkers and present current evidence of their potential to address the challenge of monitoring brain ageing and stratifying the risk of neurological disease. We focus on epigenetic clocks, which can be applied across multiple tissues and organs to estimate biological ageing, as well as on blood-based epigenetic scores (EpiScores) that can directly track brain-based phenotypes, such as cognitive function, and risk factors for neurological diseases, such as lifestyle behaviours and proteomic markers of inflammation. We discuss the associations between these epigenetic biomarkers and multiple measures of cognitive health, including cognitive test data, brain MRI measures and dementia.
