Notes:
*
First-degree relative. Each three-level categorical variable (family member type and education) was recoded into a pair of dichotomous variables prior to their inclusion into the regression models to reflect the most relevant comparisons. The direction of each dichotomous variable is noted below, with the reference category listed second.
