Cox proportional hazard model for progression-free survival (univariate and multivariate analysis)

	Univariate			Multivariate
	HR	95% CI	p value	HR	95% CI	p value
BRCA status (BRCAwt vs BRCAmut)	0.45	0.28 to 0.71	<0.001	0.45	0.28 to 0.73	<0.001
Age (continuous)	1.007	0.98 to 1.03	0.61
Chemotherapy Response Score (3 vs 1–2)	0.54	0.35 to 0.84	<0.007	0.56	0.36 to 0.86	0.01
LPS-PIV (8 vs >8)	0.92	0.59 to 1.45	0.74
Residual tumor at surgery (0 vs >0 mm)	0.79	0.47 to 1.34	0.39

Values in bold are considered statistically significant (p<0.05).
BRCAmut, BRCA mutated; BRCAwt, wild-type BRCA genotype; ECOG PS, Eastern Cooperative Oncology Group; LPS-PIV, laparoscopic predictive index value.
