^aMultivariable linear regression analysis were performed with backward selection within domain, adjusted for age and sex. ^bMultivariable linear regression analysis were performed with backward selection with all factors that are significant within domains, adjusted for age and sex. ^cOR when analyzed by standard deviation, 1.502 (1.193, 1.892). ^dMultivariable linear regression analysis performed for BIS and CTQ separately due to a subset of the sample having these measures.
