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

objectiveThis study aims to understand the age patterns of smoking initiation during adolescence and young adulthood in South-West China, where the prevalence of tobacco use is reported as the highest in the country.

designA cross-sectional study.

settingThe data were derived from the China National Nutrition and Health Survey in Yunnan Province, South-West China (2010-2012).

participantsA total of 4801 participants aged 15-65 years were included. PRIMARY OUTCOME MEASURES: A survival model was used to estimate the hazard of smoking initiation by age and log-rank test was used to compare the hazard curves across subgroups (men/women, urban/rural, Han Chinese/ethnic minority).

resultsThe prevalence of current smoking among men and women were 60.4% (95% CI 58.2% to 62.6%) and 5.1% (95% CI 4.3% to 5.9%), respectively. Smoking was more prevalent among men and women of lower education and less income, as well as rural and ethnic minority women. Among the current smokers, cigarette (80.7%) was the most commonly used tobacco product, followed by waterpipe (10.8%) and pipe tobacco (8.5%). The hazards of smoking initiation were low for both men and women before the age of 15 years (1% for men and 0.05% for women); and the hazards increased quickly from age 15 years and peaked at 19years (21.5% for men and 1.0% for women). Rural and ethnic minority women were at higher risk of smoking initiation than their counterparts between 15 years and 19 years of age (χ

conclusionsFindings of this study underscore the importance to implement tobacco prevention interventions among older teens and young adults in South-West China, especially for rural and ethnic minority women.
