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

backgroundThere are little data available on the prevalence of chronic obstructive pulmonary disease (COPD) in the United Kingdom. The Northern Ireland Cost and Epidemiology of Chronic Obstructive Pulmonary Disease (NICECOPD) study is a two-stage survey to examine the prevalence of obstructive lung disease in a general population sample in the Greater Belfast area.

methodsIn stage one 4000 subjects aged 40-69 years were selected at random from the general population. They were posted a short screening questionnaire concerning respiratory symptoms. Respondents were divided into 'symptomatic' and 'asymptomatic' groups according to their responses. In stage two, a sample of symptomatic and asymptomatic subjects completed a more intensive assessment that included a detailed questionnaire on medical history, spirometry, skin allergy testing and serial peak flow measurements. Spirometric criteria for airflow obstruction were FEV1/FVC ratio of <70% with FEV1 < 80% predicted. Subjects were assigned diagnoses according to a pre-arranged protocol.

resultsThe survey was conducted from May 1999 to May 2001. There was a 67% response rate to the stage 1 screening questionnaire and 1330 responders were identified as being eligible to take part in stage 2. In total, 722 subjects completed a detailed assessment (50.8% Male, symptomatic, n = 326; asymptomatic, n = 396). COPD was diagnosed in 12.3% (8.8, 15.8) of the symptomatic and 2.2% (0.8, 3.6) of the asymptomatic group. The estimated prevalence of obstructive lung disease in the total population age 40-69 years was 14.4%: 6.3% COPD; 7.2% asthma; 0.9% with indeterminate airflow obstruction. In men, the prevalence of COPD varied from 4.9% in those aged 40-49 years to 12.3% in those aged 60-69 years and in women, varied from 1.4% in 40-49 years of age to 4.5% in 60-69 years.

conclusionThe data suggest that COPD and asthma are common conditions in the general population and should inform future plans to address the burden of disease.
