N represents number of participants in the main categories: total pediatric participants, total adult participants and total participants. n represents the number of participants in the age groups within the main categories
Percentage denominators are the number of participants for whom data was reported in that category
aNo bone or fracture data were available for infants (< 1 year of age; n = 5). These items were reported by adults as occurring in their childhood
