Survival outcome in each risk group classified by the Japanese Metastatic Renal Cancer prognostic classification (independent data set)

Risk group	n (%)	Median OS (months)	2‐year OS (95% CI)
Favorable	34 (25)	56	79 (73–86)
Intermediate	50 (37)	28	60 (52–68)
Poor	48 (35)	12	40 (31–48)
Unclassified	4 (3)	9	20 (13–27)

Favorable risk, poor prognostic factor = 0 or 1; intermediate risk, poor prognostic factor = 2; poor risk, poor prognostic factor = 3 or 4; CI, confidence interval; OS, overall survival.
