Systematic Identification of Novel Ferroptosis-Associated Multigene Models for Predicting Patient Prognosis Based on Endometrial Cancer

Table 1

The 4-gene signature model in clinical application, information on age, grade, stage as well as risk score.

Variables	Univariable analysis				Multivariable analysis
	HR	HR. lower	HR. upper	values	HR	HR. lower	HR. upper	values
Age
(>65 vs. ≤65)	1.1	0.75	1.6	6.80E − 01	0.99	0.69	1.4	9.70E − 01
Stage
(III-IV vs. I-II)	3.5	2.4	5	1.30E − 11	2.8	1.9	4.2	8.60E − 08
Grade
(G3 vs. G1-G2)	2.1	1.4	3.1	5.40E − 04	1.4	0.84	2.2	2.10E − 01
Risk score	2.6	1.8	3.7	4.50E − 07	1.6	1.1	2.4	2.90E − 02

The bold values represents a significant difference in the COX regression analysis. As a result, we can found that risk score and stage were significantly associated with survival in both univariate analysis and multifactor analysis.
