Prognostic Relevance of STRAP Gene Copy Status in Patients Without Adjuvant Chemotherapy.

Markers	Relative Risk of Recurrence (95% CI)	P	Relative Risk of Death (95% CI)	P
Amplification (n = 20) versus normal diploidy (n = 27)	0.27 (0.11–0.68)	.005	0.26 (0.10–0.70)	.004
Deletion (n = 48) versus normal diploidy (n = 27)	0.71 (0.35–1.36)	.280	0.60 (0.25–1.05)	.130
Amplification (n = 20) versus no amplification (n = 75)	0.34 (0.15–0.79)	.011	0.37 (0.16–0.85)	.020

The relative risk has been calculated using a multivariate Cox proportional hazard model. The relative risk of patients with normal diploidy of STRAP is 1.
