Table 3. . Final cox proportional hazard model for mortality.

Parameter	Parameter Estimate	Standard Error	p-value	Hazard Ratio	95% CI
Was there initial (>5%) weight loss upon starting immunotherapy? Yes vs No	0.91	0.32	0.0052	2.48	1.31	4.68
Albumin <3.5 g/dl	1.37	0.39	0.0005	3.95	1.83	8.54
Age when started immunotherapy	0.81	0.36	0.026	–	–	–
Age†	-0.01	0.00	0.0249	–	–	–
