Note: Variables = Modified ICF-block or chapter -items; SkelDys = people with skeletal dysplasia; Number of n is smaller in the variable “interference of pain”, because it illustrates those replies with pain from mild to extremely hard pain (no replies from people with no pain); ^a = a sum variable (interval scale variable); ^b = an ordinal scale variable; The bigger the mean rank and the median is, the more the group had problems in the variable; Mann-Whitney U-test for interval and ordinal scale variables
