↵* Adjusted for survey cycle, age, sex, race/ethnicity and sex:survey interaction. To clarify the interaction, the adjusted model was stratified by sex, with the survey effect shown in the lower portion of the table for comparison. Unadjusted results are from univariate analyses with covariates age, sex, race/ethnicity, survey cycle and sex:survey interaction.
