Patterns of use of dry powder inhalers versus pressurized metered-dose inhalers devices in adult patients with chronic obstructive pulmonary disease or asthma: An observational comparative study.
Observational study in Chronic respiratory disease, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 23 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
Numerous patients with chronic obstructive pulmonary disease (COPD) and asthma do not use inhaler devices properly, which can contribute to poor disease control. The objective of this study is to assess the technical and safety use of dry powder inhalers (DPIs) versus pressurized metered-dose inhalers (MDIs) in adult patients with COPD or asthma in Lebanon. A concurrent, prospective comparative observational study was conducted at one hospital and 15 community pharmacies in Lebanon. Over a period of 18 months, 246 questionnaires were filled. Patients included were adults with COPD or asthma. Answers were entered into the Statistical Package for Social Sciences software and excel sheet. T-test and correlation were used to analyze the results; 67.8% and 38.4% of those using DPIs and MDIs, respectively, performed the exact technical steps adequately ( p = 0.003, relative risk: 2.134, 95% confidence interval: 0.910-4.842). When compared to MDI, a higher percentage of DPI users found their devices easy to use. Moreover, 81.4% of the MDI users found difficulty in coordinating between pressing the canister and inhaling. Rates of exacerbations were significantly higher in MDIs vs. DPI users (59.4% vs. 21.7%). Overall, 44.31% of patients did not receive education from their healthcare professionals about the devices. A significant number of COPD/asthma adult patients do not use their devices properly. Even though DPIs were significantly easier to use, proper education on the technical use of all types of inhalers is needed.
