Multivariable Cox Model of Progression-Free Survival in Women With Ovarian Cancer

Variable	P	Hazard Ratio	95% CI
Residual disease	.003	1.80	1.24 to 2.59
Stage	.002	2.43	1.30 to 4.54
Grade	.027	1.76	1.03 to 2.99
BRCA½ mutation status	.019	0.61	0.39 to 0.94

NOTE. Residual disease was a binary variable (0 for ≤ 1 cm and 1 for > 1 cm). Stage was a binary variable (0 for stages 1 and 2 and 1 for stages 3 and 4). Grade was a binary variable (0 for grades 1 and 2 and 1 for grade 3). The patient with a tumor harboring both a BRCA1 and a BRCA2 mutation was only counted once.
