Note: Variables = Modified ICF-block or chapter -items; SkelDys = people with skeletal dysplasia; ^a = a sum variable (interval scale variable); ^b = an ordinal scale variable; ^c = a nominal scale variable; ^d = Of those who use a car; Used statistical analysis: Mann-Whitney U-test for interval and ordinal scale variables and Pearson Chi-Square -test for nominal scale variables. The bigger the mean rank and the median is, the more the group had problems in the variable
