  1. Notes: 1Age is rounded down to the nearest year. The event counts for each age are based on the participants reported age at a specific event. Participant are included in the overall N (denominator) for each age group until their age at last visit (the oldest age recorded). Participants are only counted once per age. For ages 0–1 Year, the sum of the number of unique prescription/non-prescription medications taken at age 0 and at age 1 is summarized
