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 joint conditions data were available for infants (< 1 year; n = 5)
