Corrigendum to “Dyspnea Index: An upper airway obstruction instrument; translation and validation in Swedish”

We regretfully must inform you of an error in our above and below mentioned article. During our further work with the material that was the base of our article, we realized that two patients were wrongfully included in the study. We had an ethics approval to include patients from the age of 15 but mistakenly included two patients that were 14 years old. The patients' parents had signed an informed consent and since the participation of the two patients consisted of them filling in a questionnaire they were not harmed or in danger of getting harmed. A corrected manuscript has been sent.

We apologize for this error.
