* Kruskal–Wallis global for a p = 0.05, using as an answer, the HRQoL according to KS9, and as a factor, the level of physical activity PA: 1 (The child does not exercise.), 2 (The child does some occasional physical activity or sport), 3 (The child does physical activity several times a month), or 4 (The child does sports or physical training several times a week). ** Mann–Whitney post hoc U analysis with Bonferroni correction factor having p = 0.017. KS9: derived variable for the HRQL (values 1–5). PA: frequency of physical activity (values 1–4). MEAN DIF: difference between the average values of KS9 for each level of PA. MEDIANS DIF: difference between the median values of KS9 for each PA level.
