Pair-wise comparisons using log-rank test between gene expression profiling (GEP) classes for distant metastasis-free survival, overall survival, and disease-specific survival

	Pair-wise comparison	P-value
Distant metastasis- free survival	GEP class 1A vs. 1B	0.438
	GEP class 1A vs. 2	< 0.05 (p = 1.27 e-8)
	GEP class 1B vs. 2	< 0.05 (p = 1.22 e-4)
Overall survival	GEP class 1A vs. 1B	0.349
	GEP class 1A vs. 2	< 0.05 (p = 8.21 e-4)
	GEP class 1B vs. 2	< 0.05 (p = 2.97 e-3)
Disease- specific survival	GEP class 1A vs. 1B	0.392
	GEP class 1A vs. 2	< 0.05 (p = 1.40 e-5)
	GEP class 1B vs. 2	< 0.05 (p = 1.39 e-3)
