  • Data are expressed as median (IQR).

  • *Significantly different between baseline and follow-up (Bonferroni-corrected level of significance: p<0.025 (0.05/2)).

  • †NA=not applicable; because the indoor footwear was provided only after baseline measurement. Please note that values are median; hours of indoor and regular footwear cannot be added up.
