Cigarette and e-cigarette smoking as associated factors of gingivitis in 15-year-olds: a cross-sectional study in Poland.
Article in Scientific reports, 2026. 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
Periodontal disease can affect subjects in every age including childhood and adolescence. In adolescents its prevalence, extent and severity can be modified by smoking habit. To assess the association of cigarette/e-cigarette smoking and gingival health in Polish 15-year-olds a cross-sectional study including clinical assessment of periodontal health (gingival bleeding, depth of periodontal pockets, loss of attachment) and self-administered questionnaire (sociodemographic factors, oral health-related knowledge and behaviors) was carried out. Appropriate statistical tests were performed, with significance set at p < 0.05, and 95% confidence intervals (CI) were calculated. Gingival bleeding occurred in 25.1% of 992 participants, PPD = 4-5 mm in 0.7%, CAL in 1.1%. Gingival bleeding was reported in the area of 3.18 (standard deviation - SD = 7.15) teeth on average with the mean number of teeth affected higher in boys than in girls (3.92 vs. 2.52; p = 0.002) and similar in rural and urban residents (3.09 vs. 3.28; p = 0.675). The mean number of teeth with dental calculus was 2.40 (SD = 5.66). 7.2% respondents smoked cigarettes, 11.7% e-cigarettes, both were associated with presence of gingival bleeding (OR = 2.5; p < 0.001 and OR = 1.92; p = 0.002, respectively). The association remained strong after adjusting for sociodemographic factors and oral behaviors (aOR = 2.54; p < 0.001 and aOR = 1.85; p = 0.004). As cigarette or e-cigarette smoking was correlated with gingivitis in Polish 15-year-olds anti-smoking recommendations should be part of oral health education in teenagers. Regarding cigarette smoking association with gingivitis in 15-year-olds in Poland, nationwide anti-smoking recommendations should be incorporated into youth education programs on general and oral health. Dentists, when examining adolescents, should pay attention to unhealthy habits, including smoking, in the context of periodontal health and provide individualized education.
