↵* Number may differ from totals because of “don't know,” refused, or missing responses.
↵† Percentage of population estimates adjusted for National Health Interview Survey sampling design.
↵‡ χ2 Test when the P value is located on a row of a main effect. P values for a general linear contrast comparing a row's percentage to its reference level are located on the level (category) within the main effect.
↵§ Percentages should be interpreted with caution because the relative standard error is >30%.
↵‖ Count and unadjusted percentage are not shown because there are <30.
