Percentages were calculated on the basis of the number of cases that could be evaluated; data were not available for all cases. Percentages may not total 100 because of rounding.

P values were calculated with the use of Fisher exact test or the chi-square test and refer to differences between the cases 14 years or younger and older than 18 years.
