Age, cumulative psychosocial risk factors, and health disparities in U.S. adult cigarette smoking: 2002-2019.

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
backgroundUnderstanding psychosocial factors that underpin smoking disparities is important for developing targeted interventions to reduce tobacco use and its associated adverse health consequences. This study investigated associations between cumulative psychosocial risks, age, and the interplay of these two factors in U.S. smoking disparities over time.
methodsParticipants included adults aged ≥ 18 years in the 2002-2019 US National Survey on Drug Use and Health. Psychosocial factors were combined into a cumulative-risk index with four levels: No-, Low-, Moderate-, and High-risk. Logistic regression analyses tested whether smoking prevalence varied by risk level and age over time.
resultsGreater cumulative risk was associated with higher smoking prevalence. Using No-risk group prevalence (4.2%) as the comparator, smoking prevalence was greatest in the High-risk group (50.8%; OR = 20.9 [95% CI, 19.8-22.0]), followed by the Mod-risk group (29.7%; OR = 5.8 [5.6-5.9]), and low-risk group (15.2%; OR = 2.4 [95% CI, 2.4-2.5]). Importantly, these disparities persisted over time. Smoking prevalence declined across time in all age groups under age 65 and the rate of decline decreased with age: Age 18-25 showed the greatest decline (34.4% to 13.7%; OR = .88 [95% CI, .88-.88]), followed by age 35-49 (29.4% to 20.8%; OR = .95 [.94-.95]), age 26-34 (30.2% to 22.4%; OR = .95 [.94-.95]), and Age 50-64 showed the slowest decline trend (21.3% to 18.8%; OR = .96 [95% CI, .96-.97]). No significant decline over time for age 65 + years was observed (10.4% to 8.7%; OR = 1.00 [.98-1.01]). There was a significant association of risk level and age in changes of smoking prevalence over time. For ages 18-25 and 35-49, smoking prevalence declined over time across all risk levels. For Ages 26-34, smoking prevalence decreased between 2012 and 2019 across all risk levels but not during 2002-2011. However, for ages 50-64 and 65 + , smoking prevalence was stable for all risk levels between 2002 and 2019.
conclusionsDespite overall declines in smoking prevalence, disparities by cumulative risk levels and age remained steady and substantial over nearly two decades. Including consideration of smoking disparities by cumulative risk levels and age may enhance the development of more targeted and effective interventions to reduce smoking prevalence.
