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

backgroundThe relationships among obesity, accelerated biological aging, and asthma, as well as the underlying epigenetic mechanisms, remain incompletely understood.

methodsWe conducted a prospective cohort study in the UK Biobank to evaluate whether accelerated biological aging mediates the association between obesity and incident asthma. We then performed two-sample Mendelian randomization (MR) to assess the potential causal effect of accelerated biological aging on asthma from an epigenetic perspective. Epigenetic MR and colocalization analyses were used to prioritize aging-related DNA methylation (DNAm) CpG sites associated with asthma. Finally, single-cell RNA sequencing (scRNA-seq) was applied to characterize the cell-type-specific expression patterns of CpG-mapped genes.

resultsIn the UK Biobank cohort, KDM-BA acceleration and PhenoAge acceleration partially mediated the association between obesity and asthma, with proportions mediated of 4.0% and 12.2%, respectively. Two-sample MR further suggested that DNAm PhenoAge acceleration was associated with a higher risk of asthma (OR = 1.02; 95% CI: 1.01-1.03; P = 0.004). Epigenetic MR and colocalization analyses suggested that cg02010481 (JAZF1), cg17929770 (RSPH6A), cg19927816 (SYMPK; RSPH6A), cg08544331 (RUNX3), cg15498134 (RUNX3), and cg04389704 (FBXL19) were associated with a reduced risk of asthma, whereas cg16553500 (COL16A1), cg16351569, cg10036013 (FOXK1), cg11647481 (FOXK1), cg23776012 (KRT222), and cg08258403 were associated with an increased risk of asthma. In scRNA-seq analyses, JAZF1, SYMPK, FOXK1, and RUNX3 were differentially expressed across multiple immune cell types.

conclusionsThis study demonstrates that accelerated biological aging partially mediates the association of obesity with asthma and further elucidates underlying epigenetic mechanisms linking aging to asthma.
