Reversible bronchial obstruction and disease-related health status in 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
We aimed to assess whether partially reversible and fixed airway obstructions are associated with different health status profiles of chronic obstructive pulmonary disease (COPD) patients. We characterized health status profiles of outpatients over 64 years suffering from COPD with fixed (n = 181) or partially reversible obstruction (n = 95) and from chronic bronchitis with forced expiratory volume in the first second (FEV1) > 69% of that predicted (n = 109) on the basis of the Saint George Respiratory Questionnaire (SGRQ) and indexes assessing cognitive (Mini Mental State), affective (15-item Geriatric Depression Scale) and physical status (Index of Barthel, six-minute walking test) and quality of sleep (Index of disturbed sleep). The degree of group-specificity of health status profiles was assessed by discriminant analysis. The 54.1% of COPD patients with partially reversible obstruction were recognized to have a distinctive health status profile characterized by a moderate to severe impairment of all components ('Symptoms', 'Activity', 'Impacts') of the SGRQ and of select indexes of performance. According to logistic regression analysis, this health status profile was associated with FEV < 46% of that predicted (odds ratio (OR): 1.6, 95% confidence interval (CI): 1.07-2.38), the use of at least three respiratory drugs (OR: 2.28, CI: 1.46-3.57) and living alone (OR: 2.01, 95% CI: 1.3-2.29). COPD patients with fixed obstruction had a very heterogeneous health status. Research is needed to verify whether the unfavorable health status profile typical of a subset of COPD patients is associated with a distinctive prognosis and can be improved by dedicated therapeutic interventions.
