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
objectiveBased on protection motivation theory (PMT), this study aimed to examine the current status of e-cigarette cessation intention and cessation behavior, as well as their associated factors, among adult e-cigarette users in China.
methodsThis was a cross-sectional study. The data were derived from a nationwide "E-cigarette Use Survey" conducted in 2023, covering 31 provinces (municipality, autonomous region) in China. A total of 550 current e-cigarette users aged 18-44 years were selected as the study population. After adjusting for sociodemographic variables, multiple linear regression models were used to identify factors associated with e-cigarette cessation intention, while binary Logistic regression models were applied to examine factors associated with e-cigarette cessation behavior. In addition, subgroup analyses were conducted according to smoking status to explore potential differences among exclusive e-cigarette users and dual users of e-cigarettes and combustible cigarettes.
resultsThe mean score of e-cigarette cessation intention was 3.52±0.96, and 31.64% of participants reported having attempted to quit e-cigarettes. After adjustment for covariates, cessation intention was associated with both the threat appraisal and coping appraisal pathways within the PMT framework. Specifically, in the threat appraisal pathway, severity (
conclusionPMT provides a valuable theoretical framework for understanding e-cigarette cessation among adults. Factors related to the threat appraisal pathway are associated not only with cessation intention but also with actual cessation behavior. More-over, the associations of PMT-related factors vary across different smoking status subgroups. These findings suggest that future e-cigarette control policies and interventions could focus on enhancing risk perception and cognitive awareness, and develop more targeted cessation strategies for specific subgroups.
