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

backgroundAlthough the epidemiology of chronic airway disease (CAD) has been investigated in several population-based studies, the findings of these studies are diverse. We aimed to investigate the prevalence of CAD and its associated factors in urban northern China.

methodsA cross-sectional study was conducted among 29,359 Chinese adults aged ≥20 years. All participants were randomly recruited from two urban communities in Beijing and asked to complete a self-administered questionnaire that enquired about the demographic characteristics as well as the diagnosis of CAD and CAD-related symptoms.

resultsIn all, 26,166 participants completed the questionnaire, with the response rate being 89.1%. The prevalence of diagnosed CAD was 9.0% among men and 7.2% among women, with a total prevalence of 8.1%. Furthermore, 11.5% of the investigated subjects had CAD-related symptoms. Women had a lower risk of developing wheezing, cough, dyspnea, and diagnosed CAD than men (P<0.05). The frequency of CAD-related symptoms and diagnosed CAD was greater among elderly persons than among those who were younger (P<0.01). Subjects with a smoking habit were more susceptible to CAD-related symptoms and diagnosed CAD (P<0.01). Additionally, individuals with CAD-related symptoms were more likely to be diagnosed with CAD, compared to those without these symptoms (P<0.01).

conclusionsCAD is a common respiratory disease in urban northern China. Female gender might be a protective factor against CAD, while age and smoking are risk factors for the disease.
