  1. aCorrelates are corrected for age, gender, GMFCS-level, BMI and CP subtype, as these variables confounded the relationships (change of more than 10% in β).
  2. bCategorical correlates were coded in the following manner: gender: female = 0, male = 1; GMFCS-level: GMFCS-level 1 = 0, GMFCS-level 2 and 3 = 1; CP subtype: unilateral = 0, bilateral = 1.
  3. cPercentage of time per 24 hours spent in dynamic activities.
  4. CP = cerebral palsy; GMFCS = Gross Motor Function Classification System; PASIPD = Physical Activity Scale for Individuals with Physical Disabilities; BMI = Body Mass Index.
