Propensity Score Analysis: Risk of Death for Patients Treated with Complex vs. Intermediate Radiation Therapy Planning

Analytic Method	Overall Survival		Lung Cancer-specific Survival
	Hazard Ratio†	95% CI††	Hazard Ratio	95% CI
Entire sample*	0.84	0.75–0.95	0.81	0.71–0.93
Entire sample, propensity score quintiles	0.84	0.74–0.95	0.81	0.71–0.93
Matched sample	0.82	0.73–0.92	0.78	0.68–0.90

^*The hazard ratio for the entire sample was adjusted for propensity score

^†Represent the hazard or death for a patient treated with complex compared with intermediate radiotherapy planning
