	Exp (b)*	95% C.I.	p-value†
Overall Survival, all patients
Age (1: above median; 0: below median)	2.21	1.33–3.67	0.002†
PTT (1: sarcoma; 0: carcinoma)	2.65	1.57–4.46	< 0.001†
Adjuvant therapy (1: yes; 0: no)	0.69	0.43–1.12	0.14
Recurrence Free Survival, all patients
PTT (1: sarcoma; 0: carcinoma)	2.76	1.68–4.54	< 0.001†
Magnitude (1: other, 0: wedge)	0.54	0.29–0.98	0.05

*Exp (b) = Hazard Ratio

† Two-tailed p-value; < 0.05 considered statistically significant.
