Lymph node metastasis predictive model without CXC chemokines/receptors.

Variable	Odds ratio	p-value	VIF
PSA (Preoperative)	1.05 (1.01–1.09)	0.0241	1.001
Primary Gleason Score	4.52 (1.84–11.1)	0.0009	1.001
Multivariable model 1:
Lymph Node Stage (N0 or N1) = Primary Gleason Score + PSA (Preoperative)
p-value < 0.001
AUC = 0.847 (0.765–0.928)

AUC, area under the curve; PSA, Prostate-Specific Antigen; VIF, Variance Inflation Factor.

Multivariate logistic regression analysis was performed to identify independent predictors of lymph node metastasis in PC using clinical information (preoperative PSA and primary Gleason score) as explanatory variables (Model 1).
