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

backgroundExposure to smoke from biomass combustion is a significant environmental risk factor for chronic obstructive pulmonary disease (COPD). Through epigenome-wide association studies (EWAS), changes in DNA methylation levels associated with pathological conditions can be identified. We aimed to determine the methylation patterns in genes involved in the development of COPD resulting from exposure to biomass-burning smoke (COPD-BBS). MATERIALS AND

methodsEWAS was conducted on induced sputum samples from 45 women with stable COPD (COPD-BBS) exposure and 45 women exposed to BBS but without the disease (BBES). Proteins whose genes showed significant differences in methylation and were soluble in the induced sputum supernatant were quantified.

results205 CpG sites were found differentially hypomethylated, and 420 were hypermethylated. The top 50 show genes associated with lung remodeling (

conclusionsGene methylation changes are linked to lung remodeling, immune response, mucus production, and xenobiotic metabolism. Hypermethylation of the cg08450425 site (
