Hazard ratios (HRs) of autism among Kawasaki disease patients during the 5-year follow-up period from the index ambulatory visits or inpatient care from 1997 to 2005.
| Total | Patients with Kawasaki Disease | Patients without Kawasaki Disease | ||||
|---|---|---|---|---|---|---|
| Development of autism | NO. | (%) | NO. | (%) | NO. | (%) |
| 5-year follow-up period | ||||||
| Yes | 4 | 0.12 | 2 | 0.36 | 2 | 0.07 |
| No | 3,374 | 99.88 | 561 | 99.64 | 2,813 | 99.93 |
| Crude HR (95% CI) | 5.01 (0.71–35.58) | 1 | ||||
| Adjusted HR (95% CI) | 4.81 (0.68–34.35) | 1 | ||||
Notes: Total sample number = 3,378. Both crude and adjusted HRs were calculated by Cox proportional hazard regressions, and stratified by age and sex. Adjustments are made for patients’ sex, age, asthma, atopic dermatitis, and allergic rhinitis. * Indicates p < 0.05;** Indicates p < 0.01; *** Indicates p < 0.001.
