Time-line of the evaluation. The first evaluation was usually done just before the monitor and the microphones were applied on to the patient. The starting point of the recording was chosen individually for each child, accounting for their typical sleep schedule. Evaluations by the nursing staff naturally were only done in an inpatient setting. The last evaluation took place the morning after the recording, when the monitor was collected by staff. VCD-D = verbal category descriptive score for cough at daytime; VCD-N = verbal category descriptive score for cough at nighttime; ACT = Asthma Control Test; Score-NS = score for cough during recording as perceived by nursing staff (only in-patients); PCQ = pediatric cough questionnaire; PC-QoL = parent-proxy quality of life questionnaire for pediatric chronic cough
