Enrollment strategy for enhanced NKI-RS.

Age range	Target enrollment
6–10	150
11–20	150
21–30	100
31–40	75
41–50	100
51–60	125
61–70	150
71–85	150

This figure shows the age range in years with corresponding enrollment targets for the NKI-RS. The total enrollment is 1000 individuals ages 6–85 years in a 4-year period. There is intentional oversampling at the ends of the age range due to the rapidity of developmental changes associated with youth and older age.
