The Risk Estimation of the Analyzed Variables for Presence of CTCs in Peripheral Blood of Patients Using Multivariate Logistic Regression

Circulating Tumor Cells	Variables	P Value	OR	95% CI
CTC EP*	Positive SOCS1 expression	< .001	0.07	0.03-0.13
CTC EMT†	Grade 3	.036	2.42	1.06-5.52
Positive APC expression	.063	2.32	0.96-5.66
CTC any‡	Positive CXCL12 expression	.025	3.08	1.15-8.26
Positive SOCS1 expression	< .001	0.10	0.04-0.25

^*− 2 Log likelihood = 78.55; R² (Cox & Snell) = 0.58; R² (Nagelkerke) = 0.78.

^†− 2 Log likelihood = 147.91; R² (Cox & Snell) = 0.04; R² (Nagelkerke) = 0.08.

^‡− 2 Log likelihood = 180.65; R² (Cox & Snell) = 0.33; R² (Nagelkerke) = 0.43.
