Median survival times for OS and DFS scores in training (n = 245) and test (n = 264) sets

OS score			DFS score
Points	Training set	Test set	Points	Training set	Test set
	Median OS months (95% CI)	Median OS months (95% CI)		Median DFS months (95% CI)	Median DFS months (95% CI)
0–1	34.3 (29.5–40.9)	31.0 (26.9–35.1)	0–2	26.0 (16.3–35.7)	15.8 (12.9–20.2)
2–3	17.4 (17.2–22.8)	17.5 (15.7–19.1)	3–5	12.6 (10.7–14.5)	10.8 (8.9–12.7)

OS, overall survival; DFS, disease-free survival; DM, diabetes mellitus; CI, confidence interval.
