Exploring the association of time-inconsistent preferences with smoking behavior: A cross-sectional survey study from Sichuan, China.

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
introductionThe high prevalence of tobacco use in China has led to a heavy social burden. There have been many studies on smoking behavior in China, but few have explored it from the perspective of behavioral economics. This study investigated the association between time-inconsistent preferences and smoking behavior.
methodsWe conducted a household-based cross-sectional survey in Sichuan Province, southwestern China, in 2022. Participants were selected using multistage stratified sampling. Data were collected through face-to-face, questionnaire-based household surveys, yielding 5446 valid responses. The smoking status of all participants was confirmed by cotinine test. Descriptive statistical analysis was performed on variables such as sociodemographic variables and time-inconsistent preference, and a binary logistic regression model was used to explore the relationship between time-inconsistent preference and smoking behavior.
resultsThe smoking rate of the survey participants was 23.87%, among which that of drinkers was 45.90%, which was significantly higher than that of non-drinkers (15.10%); 712 participants (13.07%) both smoked and drank, and the average time-inconsistent preference (time-inconsistent preferences measured over 1-month and 12-month delay periods) of smokers (mean ± standard deviation: 0.91 ± 0.14) was significantly lower than that of non-smokers (0.95 ± 0.11, p<0.001). Thus, those with weaker time-inconsistent preferences were less likely to smoke (p<0.001, adjusted odds ratio, AOR=0.276; 95% CI: 0.140-0.544). This trend was significant in both drinkers and non-drinkers, with AOR of 0.253 (95% CI: 0.093-0.693) and 0.26 (95% CI: 0.102-0.661), respectively.
conclusionsWeaker time-inconsistent preferences show a significant negative association with smoking behavior in this Chinese sample, independent of alcohol consumption. Commitment mechanisms targeting time-inconsistent preferences may hold promise for smoking cessation interventions, although efficacy requires validation through randomized trials.
