The Australian cohort used the full set of controls and in MyCode controls were age-matched. Age = age at time of survey (Australia) or age at last electronic health record retrieval (MyCode), CP = cerebral palsy. GMFCS = gross motor function classification, N = sample size, N/A = Data not available. SD = standard deviation. Note that sex is the only variable from this table included in the analyses, all other variables are provided for descriptive purposes.
