aMoE: 95% margin of error around estimated percentage (95% confidence intervals can be created from percentage ± MoE).
bAOR: adjusted odds ratio from logistic regression model that includes age group, gender, race/ethnicity (including Other Asian and Other race/ethnicity categories), education, and household income.
cYounger age: 45 to 55 years, 66 to 70 years, 76 to 80 years; Older age: 56 to 65 years, 71 to 75 years, 81 to 85 years.
dRef: reference group for comparison of variable categories.
eSignificantly differs from reference group at P<.001.
fSignificantly differs from reference group at P<.01.
gSignificantly differs from reference group at P<.05.
hThe model c-statistic assesses how well the full logistic regression model predicts which individuals use the internet to obtain information with or without help from other people.
