Overall Survival Estimates by the Risk Groups Identified by Univariate RPA

Group No.	Category	Deaths/N	Median OS (95% CI)	1-Year OS (SE)	P-value
1 (Low risk)	PSC ≤ 10%	59/72	15.1 (12.2, 36.5)	61% (6%)	0.04
2 (High risk)	PSC > 10%	96/114	11.1 (8.5, 14.2)	45% (5%)

RPA=Recursive Partitioning Analysis; PSC=Percent sarcomatoid component; OS=Overall survival
