Chronic liver failure-consortium acute-on-chronic liver failure and acute decompensation scores predict mortality in Brazilian cirrhotic patients

Table 3 Survival time and mortality according to group

Group (group symbol)	Survival time1			Mortality1
	Median (d)		Mantel-Cox	28-d mortality	90-d mortality	Death at any point during the study
	Estimate	(95%CI)	P value	n (%)	n (%)	n (%)
AD (A), n = 71	239	(166.4-311.6)	Reference group	6/67 (9.0)2	11/60 (18.3)2	18/60 (30.1)2
AD evolving to ACLF (B), n = 24	32	(0.0-64.4)	B vs A < 0.001;	12/24 (50.0)23	18/24 (75.0)23	18/24 (75.0)23
			B vs C = 0.247
ACLF (C), n = 18	11	(2.7-19.3)	C vs A < 0.001;	11/18 (61.1)23	15/18 (83.3)23	16/18 (88.9)23
			B + C vs A < 0.001
Overall, n = 113	165	(117.7-212.3)	Not applicable	29/109 (26.6)	44/102 (43.1)	52/102 (51.0)

¹Survival time and mortality for group B regards to time elapsed from the diagnosis of ACLF;

²Pearson’s χ²P values < 0.001 for comparisons across all groups;

³Fisher’s exact test P values for comparisons between groups B and C were 0.542, 0.708, and 0.431 for 28-d mortality, 90-d mortality, and death at any point during the study, respectively. AD: Acute decompensation of cirrhosis; ACLF: Acute-on-chronic liver failure.
