Association of Persistent Child Poverty County of Residence and Distance to Treating Center with Mortality

Characteristic	Multivariable model (Hazard Ratio, 95% CI)^~
Characteristic	1y survival	5y survival	10y survival
MODEL 1: Persistent Child Poverty County
Persistent Child Poverty County (ref: No)	1.05 (0.77 – 1.43)	1.30 (1.06 – 1.59)^*	1.33 (1.10 – 1.62)^*
MODEL 2: Persistent Child Poverty County and Distance to care⁺ as separate variables
Persistent Child Poverty County (ref: No)	1.03 (0.75 – 1.40)	1.27 (1.04 – 1.56)^*	1.31 (1.08 – 1.59)^*
Miles to treating center⁺	1.09 (1.03 – 1.16)^*	1.09 (1.05 – 1.14)^{^}	1.08 (1.04 – 1.13)^{^}
MODEL 3: Persistent Child Poverty County and Prolonged Distance to Care as combined variable ^×
Persistent child poverty + distance >100 miles (ref: neither)	1.42 (0.95 – 2.13)	1.80 (1.39 – 2.33)^{^}	1.79 (1.40 – 2.29)^{^}
