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
Background: Reducing adolescents' smoking rates is an important priority for global public health. Smoking intention is the most direct factor influencing smoking behavior and the best predictor of its occurrence. Smoking intention is influenced by peer smoking behavior, which strengthens adolescents' willingness to smoke. Understanding adolescents' smoking intentions and their influencing factors will be a key component of future tobacco control. This study aims to explore the relationship between peer smoking and adolescents' future smoking intentions, investigate the potential roles of beliefs and attitudes toward smoking behavior in this process, and identify the pathways among these variables. Method: A multi-stage stratified cluster sampling method was adopted to select 4,617 students from 16 junior and senior high schools in Cixi City as study subjects. The Results: Among participants, 2,359 (51.1%) were male, and 2,258 (48.9%) were female. SEM showed a significant mediating effect of beliefs and attitudes toward smoking behavior in the relationship between peer smoking and adolescents' future smoking intentions. This mediating effect consists of two pathways: the independent mediating effect of attitudes toward smoking behavior, and the chain mediating effect of beliefs and attitudes toward smoking behavior. Through bootstrap testing, the standardized total effect was 0.233 (0.185-0.280), the standardized direct effect was 0.167 (0.119-0.216), accounting for 71.7% of the standardized total effect, and the standardized indirect effect was 0.066 (0.049-0.081), accounting for 28.3%. Conclusion: Peer smoking not only directly enhances adolescents' future smoking intentions but also indirectly reinforces this effect by altering their beliefs and attitudes toward smoking behavior. Therefore, conducting precise interventions targeting beliefs and attitudes toward smoking behavior can effectively mitigate the negative influence of peer smoking, thereby providing empirical evidence for adolescent tobacco control strategies.
