Competing Interests

Honorata Hafke-Dys and Jędrzej Kociński are employed by both Adam Mickiewicz University in Poznań and the company StethoMe, and are shareholders of StethoMe. Adam Biniakowski is employed by StethoMe. Anna Bręborowicz is the StethoMe content consultant and coordinated the recordings at the hospital. All the authors were paid for their work. This does not alter our adherence to the PLOS ONE policies on sharing data and materials, and the results were obtained with all the required ethical standards and objectivity. It must be emphasized that StethoMe was established because we obtained the results presented in the manuscript and sought to change the status quo in this area of examination. This research was first inspired by the everyday situation in a GP’s office encountered by Honorata Hafke-Dys, Kociński and their children, and then by literature research and cooperation with: prof. Anna Bręborowicz from the Karol Jonscher Clinical Hospital in Poznań; Poznań University of Medical Sciences; and physicians from the Department of Pediatric Pneumonology, Allergology and Clinical Immunology.
