All prevalence and prevalence difference statistics were adjusted for the clustered sampling design of and unequal probability of selection into the data set. HS, high school.
All values are percentage points ± SEs.
In blacks, statistical evidence (P ≤ 0.05) indicated that the prevalence difference varied over the strata of this variable (modified Wald test, adjusted for the clustered sampling design of and unequal probability of selection into the data set).
In whites, statistical evidence (P ≤ 0.05) indicated that the prevalence difference varied over the strata of this variable (modified Wald test, adjusted for the clustered sampling design of and unequal probability of selection into the data set).
