The Relationship between a New Biomarker of Vagal Neuroimmunomodulation and Survival in Two Fatal Cancers

Table 3

Multivariate Cox regression survival analysis of relative risks for death in patients with non-small cell lung cancer.

Variable	B	Sig.	RR	95% CI
Chemotherapy	−0.44	0.25	0.64	0.30–1.38
Surgery	−1.20	0.01	0.30	0.11–0.79
Stage	0.48	0.01	1.61	1.24–2.10
NIM index	−0.63	0.01	0.53	0.32–0.88

Sig.: significance; RR: relative risk; 95% CI: 95% confidence interval; NIM index: neuroimmunomodulation index.
