Extracorporeal Artificial Lungs: Co-Creating Future Technology - A Qualitative Analysis.
Article in Medical devices (Auckland, N.Z.), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Terminal lung diseases such as chronic obstructive pulmonary disease (COPD) and pulmonary hypertension (PH) in progression cause a large reduction in quality of life and may lead to bilateral lung transplantation (bLTx). An artificial portable lung could provide a bridge to lung transplantation, allowing patients to remain at home and mobile for longer. To advance the development of such an artificial lung, patient feedback is essential. The aim of this study is to analyze patient acceptance about an extracorporeal artificial lung and to implement these findings into the development. Methods: In collaboration with a medical device developer, we presented a portable dummy oxygenator to patients with advanced lung disease, as potential end users. Data collection in Germany and France was based on two different methods: an online questionnaire and face-to-face interviews (F2F). Results: A total of 604 participants answered the online questionnaire and 17 participants were included in the F2F interviews. The majority of participants (COPD n=140, PH n=17) were able to walk more than 1 km with a mean suffering pressure of 2.87 and 3, respectively. Six of the 17 F2F participants who could walk <1 km were interested in an assistive device. The statistical value of Fisher's exact test for suffering pressure and desire for a portable oxygenator was 0.45. Conclusion: In patients with advanced lung disease, there is no statistically significant association between subjectively increased suffering pressure and desire for a portable oxygenator, so market introduction may be difficult. Potential end users should be implemented early in device development. Data collection via an online questionnaire combined with personal interviews has proven to be a successful approach here.
