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

backgroundThis study assessed the prevalence of COPD, its associated risk factors and co-morbidities in Sri Lankan adults.

methodsA cross-sectional study was conducted in 3 rural and 4 urban areas in 7 out of 9 provinces of Sri Lanka using a randomly selected sample of Sri Lankan adults above 18 years. The Burden of Lung Disease (BOLD) survey tool was used with pre- and post-bronchodilator spirometry. Chronic Obstructive Pulmonary Disease (COPD) was classified according to the Global Initiative on Obstructive Lung Disease (GOLD) criteria. The association of COPD with known risk factors: smoking, passive smoking, dusty job, use of firewood; and comorbidities; diabetes mellitus, past history of tuberculosis, hypertension, heart disease, stroke and lung cancer was assessed.

resultsOf 1985 subjects (45.1% male) assessed, the overall prevalence of COPD was 7.3% (95% CI 6.1%-8.4%) and the prevalence among participants above 40 years of age was 10.5% (95% CI 8.9% -12.3%). Among those with COPD, 38.9% was in stage 1, 45.8% in stage 2, 10.4% in stage 3 and 4.9% in stage 4. The prevalence of COPD was significantly higher in males (10.4%) than in females (4.7%). Of the COPD patients, 54.8% were non-smokers. COPD was significantly associated with sex, smoking and exposure to dust among the over-40-year age group. Other known risk factors such as exposure to biomass fumes and a past history of tuberculosis were not significant risk factors in this sample.

conclusionsThe prevalence of COPD in Sri Lankan adults is similar to global figures, is more common in males and the majority had less severe forms of the disease. A considerable proportion of COPD patients were females and non-smokers. Interventions focusing on targeted educational campaigns for risk groups and having facilities for spirometry at primary care level while decreasing the incidence of COPD is likely to improve early detection of the condition.
