Prognostic analysis for overall survival

Variable	Risk factor	Univariate (Kaplan–Meier) Log rank test (P‐value)	Multivariate (Cox regression model) Hazard ratio (95% confidence interval)	P‐value
FigO stage	≥II	0.0170	3.492 (1.012–12.049)	0.0478
Myometrial invasion	≥1/2	0.0111	2.341 (0.713–7.693)	0.1610
p‐ERK1/2 expression	Low	0.0203	8.202 (1.026–65.550)	0.0472

Low means no or weak expression. p‐ERK1/2, phosphorylated extracellular‐regulated kinase.
