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

objectiveTo estimate the prevalence of Chronic Obstructive Pulmonary Disease (COPD) among non-smoking Sri Lanka adults as part of a larger study which assessed the burden of obstructive lung disease (BOLD) in Sri Lanka.

resultsThe prevalence of COPD among non-smokers was 5.3%, with mild to moderate disease. Among spirometry-diagnosed COPD patients, a higher proportion was females and above age 40. Use of biomass (Odds Ratio (OR) = 1.339, 95% Confidence Interval (CI) 1.070-1.821), exposure to passive smoking (OR = 2.376, 95% CI 1.557-3.397) and female sex (OR = 1.353, 95% CI 0.992-1.648) significantly increased the odds of developing COPD and/or related symptoms. Having a chimney, reduced the risk of COPD and/or related symptoms by 29% when cooking with biomass/kerosene.
