Depth of invasion > ½*	NR	NR	3.18 (1.49-6.78)	0.003
Positive nodes	NR	NR	0.7 (0.27-1.81)	0.4
High ER	93	NR	0.22 (0.09-0.56)	0.001
High PR	93	NR	0.27 (0.12-0.63)	0.002
High Ki-67	NR	93	4.19 (1.78-9.86)	0.001
High EphA2	NR	NR	4.66 (1.87-11.59)	<0.001

^*For the clinical variables, the groups are sub-classified as low and high as follows: Stage: low (I/II) and high (III/IV); FIGO grade: low (1 or 2) and high (3); Histology: low (endometrioid) and high (non-endometrioid); Depth of invasion: low (≤ ½ myometrial thickness) and high (> ½ myometrial thickness). The same criteria for low and high expression of immunohistochemical variables were used as in Table 2. NR = not reached
