^aEach model includes age, sex and race as predictor variables.

^bChoices

Preventable: Chose to learn “preventable and not preventable” vs. only preventable

Treatable: Chose to learn “treatable and not treatable” vs. only treatable

Adult Onset: Chose to learn or did not chose to learn

Carrier Status: Chose to learn or did not chose to learn

Granular Choices: No, did not make granular choices or yes, did make granular choices

All Results: Chose to learn all or did not choose to learn all

^cAge, sex, and race are all from adolescent. Age OR is reported for increase for one year.
