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 diagnosis of chronic obstructive pulmonary disease (COPD) is confirmed with spirometry demonstrating persistent airflow obstruction.

aimTo evaluate the clinical characteristics and management of patients in primary care on COPD registers with spirometry incompatible with COPD. DESIGN AND

settingA primary care audit of Welsh COPD Read-Coded patient data from the Quality and Outcomes Framework (QOF) COPD register in Wales.

methodPatients on the QOF COPD register with incompatible spirometry (post-bronchodilator forced expiratory lung volume in 1 second/forced vital capacity [FEV1/FVC] ratio ≥0.70) were compared with those with compatible spirometry (FEV1/FVC <0.70).

resultsThis audit included 63% of Welsh practices contributing 48 105 patients. Only 19% (

conclusionPatients on the COPD QOF register with spirometry incompatible with COPD are symptomatic and managed using significant resources. If quality of care and effective resource use are to be improved, focus must be given to correct diagnosis in this group.
