a

Only results from the full original sample with the first 20 lowest p-values were presented; each multiple linear regression model with generalized estimating equations solution was adjusted for age, education, gender, race, relationship status, sexuality, newest vital sign, and short version of the Test of Functional Health Literacy in Adults based on bivariate relationships from Table 4.

b

β is the regression coefficient assessing the differences in the dependent variable (app use) between the participants with Health-ITUES total score above or equal to the cut-points and those with Health-ITUES total score below the cut-points.
