All means, proportions, and standard erros are weighted estimates of the U.S. population characteristics, taking into account NHIS’s complex sampling design.
All P values are unadjusted. P values were calculated using Wald test for continuous variables, and design-adjusted Rao-Scott Pearson chi-square test for categorical variables.
