Quantile regression analyses evaluating the relationship between race (Non-white vs white) and SF-36 physical composite score (PCS) among adolescents and young adults with moderate or severe hemophilia (n = 80)

Model	Coef.	95 % CI	p value
Crude	−24.8	−40.6, −8.92	<.01
Fully adjusted without chronic paina	−26.0	−40.8, −11.1	<.01
Fully adjusted with chronic paina	0.71	−11.0, 9.56	.89
Parsimonious without chronic painb	−26.0	−40.9, −11.0	<.01
Parsimonious with chronic painb	2.38	−13.9, 9.2	.68

^aIn addition to non-white vs white, the fully adjusted model includes age, ethnicity, health insurance status, mother’s education level, father’s education level, history of inhibitor development, bleeding disorder type, bleeding disorder severity, VERITAS-combined score, and history of inhibitor development

^bIn addition to non-white vs white, the final parsimonious model includes age, ethnicity, and history of inhibitor development
