Table 7. Hazard ratio, medians of overall survival and p-values of the two groups of patients established by the G and GC models.

Model	Risk Group	HR (CI 95%)	p-value	Median PFS (months)
G-model	Low-risk	1	0,001	NR
	High-risk	3.29 (1.57-6.91)		14,9 (9,9-44,8)
GC-model	Low-risk	1	<0,001	44,8 (33,3-NR)
	High-risk	3.43 (1.62-7.26)		16,8 (9,9-37,4)
