A comparative analysis of errors in inhaler technique among COPD versus asthma patients.
Observational study in International journal of chronic obstructive pulmonary disease. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 papers.
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
purposeThis study was designed to evaluate errors in inhaler technique in COPD vs asthma patients and to investigate the association of poor inhaler technique with patient demographics and clinical variables. PATIENTS AND
methodsA total of 509 adult patients with COPD (n=328) or asthma (n=181) who were currently using an inhaler device were included in this study. Data on patient demographics, duration of disease, type and duration of inhaler therapy, and assessment of inhaler technique were recorded.
resultsMetered dose inhaler (MDI) was the most common type of inhaler used by a similarly high percentage of patients in both COPD (83.2%) and asthma (77.3%) groups. Failure to exhale before inhaling through device (75.8% and 68.5% for MDIs; 73.2% and 71.8% for Aerolizer
conclusionIn conclusion, our findings revealed that errors in inhaler technique in terms of inhalation maneuvers and device handling were similarly common in COPD and asthma patients. Errors in certain device handling maneuvers, particularly with MDIs, were more common among asthma patients than among COPD patients and associated with female gender and shorter durations of disease and inhaler therapy.
