1 · What the graph read from it

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.

2 · The registry

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

backgroundTobacco advertisements or promotions (TAPs) can increase smoking susceptibility, especially among adolescents.China has made great progress in reducing TAPs, but has not yet achieved a total ban.This study estimated exposure to TAPs and smoking susceptibility and their changes from 2013-14 to 2021 among Chinese adolescents and examined their association.

methodsSamples of middle school (MS) students in 2013 and MS and high school (HS) students in 2021 were examined, with national and provincial representativeness. Exposure to different TAPs and non-smokers' smoking susceptibility were determined. Multilevel logistic regression was used to assess the association between exposure to TAPs and smoking susceptibility in different age groups, and whether this exposure moderated the association between anti-tobacco messages and smoking susceptibility.

resultsIn 2021, MS and HS students had high exposure to TAPs on TV/movies (63.8% and 68.8%) and at points-of-sale (POS; 41.3% and 38.3%), but MS students had slightly lower percentages than in 2013-14. In 2021, 9.2% of MS students and 12.9% of HS students who were non-smokers were susceptible to smoking, a 5.6% decrease compared to 2013-14 among MS students. Exposure to TAPs had positive associations with susceptibility after adjusting for covariates in all age groups. Anti-tobacco messages decreased smoking susceptibility, but TAPs moderated this association.

conclusionStudents had decreasing exposure to TAPs, but exposure remained high, especially at POS and TV/movies. Non-smokers had low smoking susceptibility, and this decreased over time. Exposure to TAPs was positively associated with smoking susceptibility, especially in younger students. Exposure to TAPs also reduced the benefits of anti-tobacco messages.
