Source/Notes: Health Information National Trends Survey (HINTS) 5, Cycle 2, 2018. All results account for survey weights. Italicized numbers indicate aRR being statistically significant by itself (binary or continuous predictors) or as a group (categorical predictors); a: p value of log likelihood ratio test of the whole categorical variable as a group. If this overall test is not statistically significant, the p values for the independent dummy variables inside the variable are not considered statistically significant; 95%CI: 95% confidence interval; aRR: adjusted rate ratio; HC: health care; HS: high school; Ref.: reference group
