Multivariate Cox regression analysis of selected prognostic factors in the overall survival of COAD patients.

Factors	P value	HR (95% CI)†
M stage (M1 vs. M0)	<0.001	3.51 (2.13-5.76)
N stage (N2 vs. N0 or N1)	<0.001	2.36 (1.46-3.84)
YTHDF3 (high level vs. low level)	0.015	0.58 (0.37-0.90)
Age (≥65 years vs. <65 years)	0.014	1.81 (1.13-2.89)

^†HR: hazard ratio; CI: confidence interval; the lower quartile was the cutoff value for YTHDF3.
