Trial report in Journal of aerosol medicine and pulmonary drug delivery, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04421742 (The Effect of Beclomethasone/Formoterol in Extra-fine Formulation on Quality of Life and Dyspnea is Associated to the Improvement in Small Airway Dysfunction in COPD Patients. A Pilot Study), which is not on this map. Cited by 28 papers, 1 of them a synthesis that pooled it.

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.

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.

Abstract

backgroundInhaler mishandling is a common issue among patients suffering from asthma and is associated with poor clinical outcomes and greater consumption of health-care resources. Ease of use can improve inhaler technique and, possibly, patients' preference for their inhaler device, which in turn may lead to better adherence to therapy.

methodsThis study investigated usability characteristics of NEXThaler(®) versus two other dry powder inhalers (DPIs; Diskus(®) and Turbuhaler(®)). Sixty-six adult patients with asthma (mean age 42.9±17.7 years) and with no previous experience of using a DPI were included in a randomized crossover comparison of the three devices. The main measures of usability were the number of steps failed for each device and the number of people who were able to use the device successfully (effectiveness), the time it took patients to set up the device and the time to read the instructions for use (IFU; efficiency), and patient preferences (satisfaction). Inhaler technique was evaluated after the IFU leaflet was read.

resultsNEXThaler was found to be superior to the other two DPIs in terms of the number of device use failures (p<0.001), time to set up (p<0.001), and time to read IFU (p<0.001). Additionally, the proportion of participants who completed a successful inhalation without any errors at all was significantly higher for NEXThaler than for Diskus and Turbuhaler (p<0.001). Patients rated NEXThaler as the easiest to use and most preferred inhaler to own (p<0.001).

conclusionsNEXThaler displayed better usability compared with Diskus and Turbuhaler. The improved usability and higher satisfaction with the device may contribute to increased patient adherence to asthma treatment.
