Multivariate Cox-regression analysis of OS and PFS by PCI and PSDSS.

	Overall survival (OS)		Progression-free survival (PFS)
	HR (95% CI)	^#	HR (95% CI)	^#
PCI	1.16 (1.04–1.30)	0.008	1.11 (1.03–1.20)	0.005
PSDSS	0.93 (0.82–1.06)	0.271	0.97 (0.89–1.05)	0.403

HR, hazard ratio; CI, confidence interval; PCI, Peritoneal Cancer Index; PSDSS, Peritoneal Surface Disease Severity Score.
