Table 2. Comparison of the nomogram (combined model) with age, TNM stage and prognostic model.

Models	3-year AUC (95%CI)	P-value	5-year AUC (95%CI)	P-value
Age model	0.57 (0.50–0.63)		0.59 (0.52–0.67)
TNM stage model	0.77 (0.71–0.82)		0.72 (0.65–0.79)
Prognostic model	0.71 (0.65–0.78)		0.75 (0.68–0.81)
Nomogram (combined) model	0.80 (0.75–0.85)		0.79 (0.74–0.85)
Nomogram vs. age model		<0.001		<0.001
Nomogram vs. stage model		<0.04		<0.001
Nomogram vs. prognostic model		<0.001		0.054
