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

backgroundDNA methylation patterns are heritable but can change over time and in response to exposures. Lower global DNA methylation, which may result in increased genomic and chromosomal instability, has been associated with increased cancer risk. Physical activity is a modifiable factor that has been inversely related to the risk of cancer. Changes in DNA methylation may be a mechanism by which lifestyle and environment factors influence disease. We investigated the relationship between DNA methylation and physical activity in a sample of women enroled in The Sister Study, a large United States (U.S.) cohort study of women aged 35-74 years with a family history of breast cancer.

methodsGlobal DNA methylation was measured using bisulphite-converted DNA and pyrosequencing of a LINE-1 repetitive sequence in the peripheral blood of 647 non-Hispanic white women. Physical activity (average hours per week) was retrospectively assessed for three time periods: childhood (ages 5-12), teenage years (ages 13-19) and the previous 12 months.

findingsCompared with women with physical activity levels below the median for all three time periods, those at or above the median physical activity for one (β = 0.20, 95% confidence interval (CI): -0.10, 0.49), two (β = 0.22, 95% CI: -0.08, 0.52) or all three (β = 0.33, 95% CI: 0.01, 0.66) time periods had increased global methylation.

interpretationMaintaining higher levels of physical activity over these three time periods was associated with increased global DNA methylation, consistent with reported associations between exercise and decreased cancer risk.
