Predictors of Cessation Readiness among Cigarette Smokers Presenting for Low-Dose CT Lung Cancer Screening in Community Settings (WF-20817CD).

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
backgroundTo plan cessation services and advance health equity, understanding factors related to cessation readiness and differences among patients presenting for lung cancer screening (LCS) is imperative.
methodsWe recruited smoking patients, ages 55 to 77 years, presenting for LCS in 26 community-based imaging clinics participating in an NCI Community Oncology Research Program site-randomized trial (WF-20817CD, UG1CA189824). We collected outcomes of smoking cessation readiness to change and quitting self-efficacy immediately prior to screening. Linear mixed models were constructed with site random effects to assess associations of outcomes and baseline characteristics.
resultsParticipants (N = 1,094; age = 63.7; 81.9% White, 13.3% Black, 2.6% Hispanic, 2.3% American Indian, 20.2% nonmetro) were even by gender (50.8% women) and educational attainment (51.1% ≤ high school education). Participants smoked an average of 17.2 cigarettes per day (SD = 9.6), with a mean pack-year of 46.1 (SD = 25.0). Predictors of increased cessation readiness included the following: being a man, increased worry about lung cancer, increased perceived benefits of quitting, a quit attempt within the past year, and smoking ≤10 cigarettes per day. Predictors of increased quitting self-efficacy included the following: non-White race/ethnicity, men, less education, no use of other tobacco products, increased perceived benefits of quitting, a quit attempt within the past year, and smoking ≤10 cigarettes per day.
conclusionsTo support cessation among patients undergoing LCS, imaging clinics and health systems should recognize that prescreening readiness to quit varies by population subgroups. Imaging clinics may benefit from a tailored approach that works with patients "where they are." IMPACT: These findings suggest that gender, race, and ethnicity are associated with smoking cessation readiness and quitting self-efficacy.
