Table S7. Five-year RFI assessed by AUC in multiple staging systems in training, internal validation, and external validation group.

RFI	Training group				Internal validation group				External validation group
RFI	AUC (95% CI)	P^a	P^b	P^c	AUC (95% CI)	P^a	P^b	P^c	AUC (95% CI)	P^a	P^b	P^c
RFI, recurrence-free interval; AUC, area under the curve; CS, clinical stage; PS, pathologic stage. ^a, Contrast estimate with PS as reference; ^b, Contrast estimate with CPS+EG as reference; ^c, Contrast estimate with Neo-Bioscore as reference.
