Multivariable analysis of the effect of parameters on PFS and OS.

Parameters	PFS		OS
	HR (95% CI)	p-Value	HR (95% CI)	p-Value
Age at diagnosis (≥65 vs. <65)	0.9 (0.4–1.7)	0.78	2.1 (1.1–4.2)	0.03
Tumour location (right vs. left)	1.5 (0.6–3.7)	0.43	0.9 (0.4–2.3)	0.86
Metastatic at diagnosis (yes vs. no)	2.7 (1.3–5.9)	0.009	2 (1–4)	0.05
RAS status (wildtype vs. mutant)	0.7 (0.3–1.4)	0.31	1.7 (0.8–3.4)	0.14
Lung only metastasis (yes vs. no)	0.8 (0.2–3.1)	0.81	0.7 (0.2–2.6)	0.64

PFS (progression-free survival), OS (overall survival), HR (hazard ratio).
