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

backgroundHigher smoking prevalence in less educated persons and manual workers is well known. This study examines the independent relationship of education and occupation with tobacco use.

methodsWe used anonymized data from a nationwide population survey (30,617 men and 33,934 women). Education was divided into junior high school, high school, or university attainment. Occupation was grouped into upper non-manual, lower non-manual, and manual. Poisson regression models stratified by age and gender were used to estimate adjusted prevalence ratio (PR) and 95% confidence interval (CI) for current smoking.

resultsAfter adjustment for covariates, education, and occupation, education was significantly related to current smoking in both genders; compared to university graduates, PRs of junior high school graduates aged 20-39, 40-64, and ≥65 were 1.74 (95% CI, 1.53-1.98), 1.50 (95% CI, 1.36-1.65), and 1.28 (95% CI, 1.08-1.50) among men, and 3.54 (95% CI, 2.92-4.30), 2.72 (95% CI, 2.29-3.23), and 1.74 (95% CI, 1.14-2.66) among women, respectively. However, significantly higher smoking prevalence in manual than in upper non-manual was found only in men aged 20-64; compared to upper non-manual, the PRs of manual workers aged 20-39, 40-64, and ≥65 were 1.11 (95% CI, 1.02-1.22), 1.18 (95% CI, 1.10-1.27), and 1.10 (95% CI, 0.89-1.37) among men, and 0.95 (95% CI, 0.75-1.20), 0.92 (95% CI, 0.75-1.12), and 0.46 (95% CI, 0.22-0.95) among women, respectively.

conclusionsIndependent of occupation, educational disparities in smoking existed, regardless of age and gender. Occupation-smoking relationship varied with age and gender. Our study suggests that we should pay attention to social inequality in smoking as well as national smoking prevalence.
