Table 2 Overall appearance of adjusted hazard ratio

Tumor type	Cut-off value	HR (95%CI, P value) - OS	HR (95%CI, P value) - RFS
EGC	PM = 0.5 cm	0.300 (0.074-1.218, 0.092)	0.310 (0.050-1.927, 0.209)
EGC	PM = 1 cm	0.541 (0.158-1.850, 0.327)	0.494 (0.112-2.177, 0.351)
EGC	PM = 2 cm	1.208 (0.433-3.366, 0.718)	1.367 (0.379-4.928, 0.632)
EGC	DM = 1 cm	9.229 (0.479-177.727, 0.141)	12.979 (0.174-969.978, 0.244)
EGC	DM = 2 cm	2.350 (0.520-10.620, 0.267)	2.354 (0.444-12.476, 0.314)
AGC	PM = 0.5 cm	1.122 (0.658-1.915, 0.672)	0.870 (0.535-1.417, 0.577)
AGC	PM = 1 cm	0.922 (0.608-1.398, 0.703)	0.917 (0.623-1.351, 0.661)
AGC	PM = 2 cm	0.979 (0.674-1.422, 0.911)	1.050 (0.738-1.495, 0.786)
AGC	DM = 0.5 cm	0.615 (0.366-1.032, 0.066)	0.772 (0.458-1.302, 0.332)
AGC	DM = 1 cm	0.706 (0.466-1.070, 0.101)	0.852 (0.570-1.273, 0.434)
AGC	DM = 2 cm	1.109 (0.787-1.563, 0.554)	1.338 (0.952-1.882, 0.093)

In the EGC group, we excluded the comparison between the cases where DM < 0.5 and DM ≥ 0.5 because reliable estimates could not be obtained from such a small number of events. EGC: Early gastric cancer; AGC: Advanced gastric cancer; PM: Proximal resection margin; DM: Distal resection margin; OS: Actual 3-year overall survival; RFS: Actual 3-year recurrence-free survival.
