Normal bronchial field basal cells show persistent methylome-wide impact of tobacco smoking, including in known cancer genes.
Article in Epigenetics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05854563 (Genetics of Lung Disease), which is not on this map. Cited by 2 papers.
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.

Abstract
Lung carcinogenesis is causally linked to cigarette smoking, in part by epigenetic changes. We tested whether accumulated epigenetic change in smokers is apparent in bronchial basal cells as cells of origin of squamous cell carcinoma. Using an EM-seq platform covering 53.8 million CpGs (96% of the entire genome) at an average of 7.5 sequencing reads per CpG site at a single base resolution, we evaluated cytology-normal basal cells bronchoscopically brushed from the in situ tobacco smoke-exposed 'bronchial epithelial field' and isolated by short-term primary culture from 54 human subjects. We found that mean methylation was globally lower in ever (former and current) smokers versus never smokers (
