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

backgroundChronic obstructive pulmonary disease (COPD) is a heterogeneous, progressive pulmonary disorder with persistent respiratory symptoms resulting from abnormalities in the airways and/or alveoli and was prevalent globally in 10.3% of people aged 30-79 years in 2019. The prevalence of COPD has increased rapidly in women in the past decade. This may be due to increased tobacco use, but may also involve sex-specific factors. PURPOSE: To evaluate the prevalence of COPD in the context of sex and tobacco exposure. DATA SOURCES AND SEARCHES: Comprehensive searches of MEDLINE (OVID), EMBASE and CENTRAL were conducted for articles published from inception to July 22, 2022. STUDY SELECTION: We independently evaluated titles, abstracts and full-text articles in a duplicated two-staged process. Studies were included if they reported the prevalence of COPD as a primary outcome in the context of sex and tobacco exposure. DATA SYNTHESIS AND ANALYSIS: Pooled analysis was conducted with Review Manager 5, and heterogeneity was assessed with the I LIMITATIONS: Included articles are limited by the quality of data on tobacco smoke exposure, primarily reported as a binary risk factor, with lack of availability on duration and intensity of exposure.
