The multivariable logistic regression model for LN metastasis of PDAC

Variable	Coefficient	S.E.	OR (95% CI)	P-value
(Intercept)	−0.10	0.20	0.91 (0.61, 1.34)	0.62
CT-reported LN metastasis
No versus yes	0.79	0.35	2.19 (1.10, 4.38)	0.026
Rad-score	1.17	0.26	3.24 (1.96, 5.35)	0.0001

The predicted model = −0.10 + 0.79× (CT-reported LN metastasis =1) + 1.17 × Rad-score
