Note: HILM = Health Insurance Literacy Measure; CI = confidence interval; OR = odds ratio.
a.
Higher SURE values indicate more choice confidence.
b.
Group and percent of federal poverty level results are presented as least-squares means (95% CI) for objective knowledge, decision self-efficacy, and confidence in choice. Health insurance literacy and metal level results are presented as OR (95% CI).
c.
Numeracy results are presented as type III sum of squares for objective knowledge, decision self-efficacy, and confidence in choice. Health insurance literacy and metal level results are presented as coefficient (SE).
