Nicotine Metabolism-Related Genetic Polymorphisms Associated with Smoking Cessation in Korean Men: A Candidate Gene Association Study in a Korean Cohort.
Article in Lifestyle genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
introductionSmoking cessation is influenced by genetic and environmental factors, particularly genetic polymorphisms influencing nicotine metabolism. This study investigated the association between specific nicotine metabolism-related genetic variants and smoking cessation among Korean men.
methodsA candidate gene association study was performed targeting single nucleotide polymorphisms (SNPs) within nicotine metabolism-related genes. Participants were categorized as never, former, or current smokers. A Genetic Risk Score (GRS) was computed using significant SNPs to evaluate cumulative genetic influence.
resultsSix SNPs showed significant association with smoking cessation in a Korean cohort. A higher GRS was associated with increased odds of current smoking compared to former smoking (OR = 1.18, 95% CI: 1.12-1.25, p < 0.001).
conclusionThis study indicates a substantial genetic component in smoking cessation, highlighting the importance of population-specific approaches, and may aid personalized smoking cessation strategies based on genetic predisposition among Koreans.
