Ns vary because of missing values. The variables were standardized so that the values reported in the table are all on a 0–8 scale. Because of an administrative error, improvement in clothes fitting was only measured among those participants at 6 months who completed the assessment via mailed questionnaire and it was not measured at 18 months
