  1. Results presented as median [95% confidence interval of median]. Statistical analysis performed using Wilcoxon sign rank test. Results of the exercise test (cycle ergometry) and of the accelerometry (measured for 7 consecutive days at the right hip) did not show any significant differences between patients with CNO and HC
  2. Wpeak: maximal power in % predicted according to Godfrey-protocol [16], HRpeak: peak heart rate in % predicted according to Rowland for teenagers between 13 and 17 years [18] and Fairbarn [19] for adults. VO2peak: peak oxygen update in %predicted according to Orenstein [17], RQmax: peak respiratory quotient
