Note: Boldface indicates significant p-values.
a
Percentages and 95% CIs are weighted to the U.S. population and adjusted for all covariates in the table using multivariate regression analysis. p-values below the estimates are derived from global Wald-F tests of association between awareness and demographic, personal and family cancer history, and healthcare factors variables.
b
p-values are derived from Wald-F tests for interaction of each demographic, personal and family cancer history, and healthcare factor by survey year.
