BRFSS responses account for complex survey design and are standardized to CLUES demographic distribution on age (18–37, 38–53, >54 years), sex, and race/ethnicity.

BRFSS ACE questionnaire does not include two “Neglect” items. Overall ACE levels for CLUES patients do not include the two neglect items.
