Tobacco smoking as an endocrine disrupting chemical: An assessment through biological monitoring.
Article in Tobacco induced diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionTobacco smoke is a mixture of endocrine disrupting chemicals (EDCs), which may accelerate biological ageing.
methodsWithin this cross-sectional study we recruited adult and adolescent subjects (2013-2014) and performed biological monitoring to clarify health end points of tobacco smoking between adolescents and adults (n=620) with exposure biomarkers, i.e. CO, urinary cotinine, t,t-muconic acid (TTMA), malondialdehyde (MDA), and obtained information of behavioral factors and tobacco addiction status in South Korea. We also analyzed the 96 SNPs for metabolism, addiction, and expression differences and compared mtDNA abnormalities in buccal and blood cells.
resultsThere was an association between tobacco smoking and oxidative stress with urinary cotinine and MDA levels. Youth smokers showed lower frequency in some of mtDNA alteration, SNPs for consistent bases between buccal and blood cells, than youth non-smokers or adult smokers. Among the SNPs, the polymorphisms on SULT1A1, DRD2, and ADH1B were related to multiple of the above exposure biomarkers. Interestingly, urinary MDA or TTMA in youth were similar to those in adults (MDA, 2.7 ± 1.5 vs 2.4 ± 1.3 μM; TTMA, 74.1 ± 129.9 vs 98.8 ± 126.1 μg/L), although urinary cotinine levels were approximately four-fold lower in youth than adults (0.1 ± 0.4 vs 0.6 ± 0.9 mg/L; p<0.0001). Urinary MDA, an oxidative stress biomarker, were negatively associated with the growth rate among the adolescents.
conclusionsThe present biological monitoring study assessed the impact of combustible cigarette smoking with various exposure, susceptibility and response biomarkers to clarify how tobacco smoking differently affects adolescents and adults in South Korea.
