Univariable and multivariable predictors of cumulative late mortality

	Univariable model		Multivariable model
	HR (95% CI)	p Value	HR (95% CI)	p Value
eGFR <60 ml/min	2.27 (1.03 to 4.98)	0.041	2.22 (0.86 to 5.76)	0.099
STS-PROM score (%)	1.09 (1.04 to 1.16)^*	0.001	1.10 (1.01 to 1.20)^*	0.027
Frailty	2.44 (1.05 to 5.70)	0.039	1.96 (0.82 to 4.67)	0.129
No thoracic epidural analgesia	2.59 (1.19 to 5.65)	0.016	2.39 (1.04 to 5.49)	0.039

↵* For each increase of 1%.
eGFR: estimated glomerularfiltration rate; STS-PROM: Society of Thoracic Surgeons predicted risk of mortality.
