Results are based on generalized linear regression models controlling for demographics, health characteristics, and comorbidities as covariates

^aRespondents with depression diagnosis: those who self-reported physician diagnosis of depression and reported experiencing depression in the past 12 months

^bRespondents without depression diagnosis: those who had no self-reported physician diagnosis of depression, reported not experiencing depression in the past 12 months, and had PHQ-9 scores ≤ 4

^*P-value < 0.050 for comparison vs ‘no/minimal symptoms’ severity group

^**P-value < 0.010 for comparison vs ‘no/minimal symptoms’ severity group

^‡P-value < 0.001 for comparison vs ‘without depression diagnosis’ group
