	Annual OOP cost for asthma medications
	25^th percentile ($100) Mean (95% CI)	75^th percentile ($190) Mean (95% CI)	p-value
Hierarchical Model with Nesting at Plan-Year Levels
% of days covered by an asthma medication prescription	34.8 (34.0–35.6)	33.7 (33.0–34.3)	0.005
Rate of asthma-related hospitalizations per 100 children	1.7 (1.2–2.2)	2.3 (1.9–2.7)	0.03
