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

objectivesTo determine the prevalence and associated factors of smoking in a Chinese adolescent population.

settingA multistage, stratified cluster sampling technique was used in the present cross-sectional study conducted in Zhejiang Province of China. Based on socioeconomic status, school levels and geographical positions, 253 middle school classes, 122 academic school classes and 115 vocational high school classes located in 12 urban areas and 18 rural areas were chosen.

participantsA total of 9617 middle school students, 5495 academic high school students and 4430 vocational high school students were recruited in this survey. PRIMARY AND SECONDARY OUTCOME MEASURES: Ever, current smoking status and associated factors were collected via a self-administered questionnaire. Logistic regression models were used to examine the associations between current smoking and the associated factors. ORs with their 95% CIs were reported.

resultsOverall, the prevalence of ever-smokers and current smokers was 33.83% and 7.93%, respectively. Focused on current smokers, significantly higher risks of adolescent smoking were observed in an older age group, boys, rural areas and vocational high school. Other significant factors were parents smoking, secondhand smoke exposure, parental divorce or separation, living with family, school performance and belief that smoking is harmful.

conclusionsThe prevalence of smoking was relatively high among Chinese adolescents in Zhejiang Province. Factors related to personal characteristics, family and school were associated with adolescent smoking.
