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

backgroundThe clinical diagnosis of chronic obstructive pulmonary disease (COPD) should be considered in any patient who has dyspnea, chronic cough or sputum production, and diagnosis should be confirmed by performing spirometry in presence of airflow limitation. The aim of this study was to assess the validity of a questionnaire used to detect COPD based on spirometry findings. MATERIALS AND

methodsThe validity of a questionnaire for COPD diagnosis was examined using spirometry based on both Global Initiative for Chronic Obstructive Lung Disease (GOLD) and American Thoracic Society/European Respiratory Society (ATS/ERS) criteria for patients 35 years old and older. In total, 350 questionnaires were completed. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio and negative likelihood ratio were calculated to determine the accuracy of the questionnaire.

resultsThe sensitivity of the questionnaire in detection of airflow limitation was 8.3% and 6.7% by the GOLD and the ATS/ERS criteria, respectively; whereas, specificity was 96% by both criteria.

conclusionThe high specificity of the questionnaire indicates that the questionnaire is more capable to identify people who do not have airflow limitation; whereas, the low sensitivity of the questionnaire could underestimate the actual prevalence of COPD in the general population.
