In these randomised controlled studies the CFQ-R is followed by the Treatment Satisfaction Questionnaire for Medication (patients aged ≥12 to <18 years at the date of informed consent); remaining assessment may be performed in any order when more than one assessment is required at a particular clinic visit. f: weight and height will be measured with shoes off.
