Table 7 Multivariate binary logistic regression analysis of characteristics associated with long-term survival

		Long-term survival
Variable		OR	95% CI	p
Age at metastasis ≤ 65 years (yes versus no)		1.95	0.96–3.97	0.064
Single site metastases versus multiple sites		1.76	0.87–3.58	0.114
First-line therapy	Chemotherapy plus bevacizumab versus other	2.49	1.13–5.52	0.024
Surgical resection of metastasis (yes versus no)		3.96	1.96–8.02	< 0.001
Local non-surgical treatment of metastasis (yes versus no)		3.32	1.64–6.71	0.001
