  • See a complete list of the surgical procedures by category in Table 1. Percentages may not add to 100% because patients could have had >1 type of procedure at a given age.

  • a n equals the number of patients in the respective age category. Patients might appear multiple times across age categories because they might have had multiple visits to the registry at different ages during the study period.
