aUnweighted sample size.

bWeighted percentage for categorical factors by applying NHANES sampling weights, or weighted mean and standard error (SE) for continuous variables (e.g., age).

cP-values are based on the Rao-Scott Chi-square tests for categorical variables or weighted linear regression for continuous variables. The P-value for comparing total ORC vs non-ORC proportions was obtained from Z-test.

dEstimate of the U.S. population, NHANES sampling weighted N, representing the results.
