Increased Risk of Atopic Dermatitis in Preschool Children with Kawasaki Disease: A Population-Based Study in Taiwan

Table 2

Hazard ratios (HRs) of atopic dermatitis among patients with Kawasaki disease during a 5-year follow-up period from the first ambulatory visit or inpatient care between 1999 and 2003.

Development of atopic dermatitis	Total		Patients with Kawasaki disease		Patients without Kawasaki disease
	No.	(Percentage)	No.	(Percentage)	No.	(Percentage)
Five-year follow-up period
Yes	311	21.6	109	30.3	202	18.7
No	1129	78.4	251	69.7	878	81.3
Crude HR (95% CI)			1.43 (1.11–1.85)**		1
Adjusted HR (95% CI)			1.25 (1.01–1.54)*		1

Total sample number = 1440.
Crude and adjusted HRs were calculated using Cox proportional hazard regression.
Adjustments were made for patients’ urbanization level, geographic region, COPD, hyperlipidemia, asthma, allergic rhinitis, and heart disease.
