↵* Percentages of the population estimates were adjusted for the National Health Interview Survey sampling design.
↵† Wald 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 using t test statistics.
↵‡ Percentages should be interpreted with caution because the relative standard error is >30%.
