On log scale - proportional effects (no risk ratios)
In addition to race/ethnicity indicator variables, quantile regression models adjust for age, gender, health and mental health status variables (self-reported mental health and health status, mental and physical components of the SF-12 scale, K6 scale of severe psychological distress, PHQ-2 depression scale, list of chronic conditions, BMI), socioeconomic status variables (poverty status, education, and marital status), and interactions between race/ethnicity and education and income.
Indicates referent group used in the expenditure model. Coefficients presented for these groups are estimated using linear combinations.
Significant disparity at α=0.05 and α=0.01 levels
Significantly different from prior row’s group (same quintile) at α=0.05 and α=0.01 levels
