Tobacco use and eligibility for lung cancer screening among dental patients at an academic institution in Houston, Texas.
Article in Preventive medicine, 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
objectiveTobacco use negatively impacts oral and general health and influences dental treatment outcomes. To advance prevention, we surveyed dental patients at an academic institution to characterize their history of tobacco use and eligibility for lung cancer screening (LCS).
methodsAnonymous surveys were administered to adult dental patients at the UTHealth Houston School of Dentistry between April 2022 and October 2022. Surveys collected information on smoking history, pack-year history, health literacy, personal and family history of lung cancer, and previous LCS. Demographic variables included age, gender, race/ethnicity, and education level.
resultsAmong 432 patients (mean age: 46.4, range 18-88 years, 57.0 % female), 22.7 % were patients who currently smoked cigarettes, and 13.2 % were patients who formerly smoked. Smoking rates were highest among males (36.2 %) and patients younger than 50 (26.0 %). Among patients who currently smoked, 44.1 % met eligibility for LCS based on age and a 20+ pack-year smoking history; 43.2 % of patients who formerly smoked were eligible for LCS.
conclusionsA substantial proportion of patients are eligible for LCS; tailored cessation counseling and electronic-referral pathways could impact screening and cessation support for millions of high-risk adults who visit a dentist each year, closing a critical gap in cancer prevention.
