^aAdjusted incidence rate ratios (IRR) and 95% confidence intervals (CI) were calculated using negative binomial regression adjusting for age, sex, household income, census region, marital status (spouse in the household), education level, and health insurance type, accounting for the duration of psoriasis follow-up.

^bNon-Hispanic minority includes black, Asian/Native Hawaiian/Pacific Islander, American Indian/Alaskan Native, and multiracial.

^cAdjusted odds ratios (OR) and 95% confidence intervals (CI) were calculated using logistic regression, adjusting for age, sex, household income, census region, marital status (spouse in the household), education level, and health insurance type.
