	Infant health states
	Infant respiratory complications	Infant neurologic complications

Long-term TTO (N = 137)
Years traded
Mean (SD)	12.3 (10.9)	15.2 (12.3)
Median [25%–75%]	10 [5–20]	10 [5–20]

*Responses from adults and parents of adolescents were pooled.
**Utilities were calculated assuming the maximum amount of time traded could not exceed the duration of the health state assuming a discount rate of 3%.
