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

introductionDNA methylation may be one of the biological mechanisms underlying the health benefits of physical activity (PA). Our objective was to determine the association between PA and genome-wide DNA methylation at CpG level.

methodsWe designed a two-stage epigenome wide association study. In the discovery stage, we used 619 individuals from the REgistre GIroní del COR cohort. Next, we validated the CpG suggestively associated with PA (P < 10) in two independent populations (n = 1735 and 190, respectively). Physical activity was assessed with validated questionnaires and classified as light PA (LPA), moderate PA, vigorous PA, moderate-vigorous PA (MVPA) and total PA. We examined linear and nonlinear associations and meta-analyzed the results in the three populations. The linear associations were meta-analyzed with a fixed-effects model and the P values of the nonlinear associations with the Stouffer and Fisher methods. We established a P value threshold that fulfilled Bonferroni criteria over the number of CpG analyzed (0.05/421,940 = 1.185 × 10).

resultsIn the meta-analyses, two CpG sites had a statistically significant nonlinear association with MVPA. cg24155427 (P = 1.19 × 10), located in an intergenic region in chromosome 1, has been previously associated with smoking, lupus, and aging. cg09565397 (P = 1.59 × 10), located within DGAT1 in chromosome 8, which encodes an enzyme involved in triacylglycerol synthesis.

conclusionsThis population-based study identified two new, differentially methylated CpG sites with a nonlinear dose-response relationship to MVPA. These associations must be additionally validated and may be considered for further research on the biological mechanisms underlying health benefits of PA.
