n = unweighted sample size; CI = confidence interval; – = not applicable. Significant differences by survey setting (p < .05) are indicated in bold type.
p-values were from two-sided t-tests and not adjusted for multiplicity.
Data were statistically unreliable because of an unweighted denominator <50 or a relative standard error >30%.
