Small airways disease is common in mild COPD and symptomatic subjects at risk with normal spirometry: baseline data from CAPTO-COPD.

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.
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
Background: Current guideline-based diagnosis of airflow limitation in COPD focuses on spirometry, which is insensitive to early small airway changes of symptomatic smokers or subjects at risk. Therefore, we sought to determine the frequency of small airways disease (SAD) in these groups compared with mild COPD, and evaluate associations with symptoms as well as health-related quality of life (HRQoL). Methods: Patients with mild COPD (post-bronchodilator forced expiratory volume in 1 s (FEV Results: We present cross-sectional baseline data from 90 COPD patients (mean±sd age 65±9 years; mean±sd FEV Conclusion: SAD is common even in symptomatic (ex-)smokers not fulfilling spirometric criteria with a similar frequency and pattern as compared to mild COPD patients. SAD is associated with impaired HRQoL, even in patients without established COPD.
