An SMD of <0.1 indicates no major imbalance. All SMD values were <0.1 in each propensity-score–matched cohort, except history of cerebrovascular disease and hypertension among patients without atopic dermatitis vs those with atopic dermatitis.

Numbers in boldface indicate significant differences (P < .05).

Minimally adjusted: adjustment for age and sex.

Fully adjusted: adjustment for age, sex, region of residence, history of diabetes mellitus, cardiovascular disease, cerebrovascular disease, COPD, hypertension, chronic kidney disease, Charlson comorbidity index, use of immunosuppressants, use of systemic glucocorticoids, allergic rhinitis, and atopic dermatitis.

Fully adjusted: adjustment for age, sex, region of residence, history of diabetes mellitus, cardiovascular disease, cerebrovascular disease, COPD, hypertension, chronic kidney disease, Charlson comorbidity index, use of immunosuppressants, use of systemic glucocorticoids, asthma, and atopic dermatitis.
