Multiple Cox Regression	FAP(+)/BCAT(N)	0.011	1.18	1.04	1.34	0.002	1.29	1.09	1.52
	Grade	0.174	1.29	0.89	1.86	0.730	1.08	0.70	1.66

	N	0.723	1.05	0.79	1.41	0.408	1.21	0.77	1.91
Final Step of Wald Method	FAP(+)/BCAT(N)	0.016	1.17	1.03	1.33	0.001	1.31	1.11	1.54
	pT	0.008	1.65	1.14	2.39	0.005	1.80	1.19	2.73

Selected independent variables were: FAP(+)/BCAT(N) expression in the primary tumor’s infiltrating front and in the lymph node metastasis, histologic grade, local invasion (pT), lymph node (N) and distant (M) metastases. ExpB with confidence interval (CI) is also included. Statistically significant values are highlighted in bold.
