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
IntroductionThis study investigates the cumulative association between adverse childhood experiences and lung cancer risk and analyzes whether a healthy lifestyle could modify this association.MethodsUsing the UK Biobank, we analyzed 156,798 participants who completed a baseline Mental Health Questionnaire. Lung cancer risk from age 30 was recorded, classifying childhood adversity severity using cumulative categories (none, mild [1-2 types], and severe [≥3 types]). We used multi-variable Cox regression and competing risk models to estimate hazard ratios (HR) between childhood adversity and lung cancer risk. Mediation analyses assessed the role of smoking.ResultsDuring a median follow-up of 41 years from age 30, 677 participants were diagnosed with lung cancer, and 401 died. Lung cancer risk increased progressively with increasing childhood adversity severity. Compared with individuals without childhood adversity, those who experienced any adversity had a 37% higher risk of lung cancer (HR 1.37, 95% CI 1.15-1.63), while those with severe adversity had an 82% higher risk (HR 1.82, 95% CI 1.27-2.62), demonstrating a clear summative effect. Participants who experienced any form of adversity had a 18% increased risk of dying from lung cancer (HR 1.18 [1.05-1.32]). Smoking severity was higher among participants with childhood adversity and accounted for approximately 40% of the observed association. Timely smoking cessation was associated with a substantially lower risk of lung cancer (approximately 75%). However, in the severe adversity group, smoking cessation did not provide a protective effect (HR 0.47 [0.20-1.09]). Smoking cessation significantly reduced lung cancer mortality regardless of adversity level.ConclusionChildhood adversity was associated with a higher risk of lung cancer in a cumulative manner, even after accounting for non-cancer death. Smoking accounted for a substantial proportion of the association between childhood adversity and lung cancer risk, and smoking cessation was associated with lower lung cancer risk across adversity levels. The association between childhood adversity and lung cancer remained robust, warranting further research to explore additional mediating pathways.
