Clinical characteristics and 28-d outcomes of bacterial infections in patients with hepatitis B virus-related acute-on-chronic liver failure

Table 3 Relationship between site of bacterial infections and grade of acute-on-chronic liver failure

Site of BIs	AD (n = 47)	ACLF-1 (n = 92)	ACLF-2 (n = 53)	ACLF-3 (n = 49)	χ2 value	P value
SBP (%)	20 (42.6)	39 (42.4)	16 (30.2)	12 (24.5)	6.093	0.107
Pneumonia (%)	14 (29.8)	36 (39.1)	20 (37.7)	23 (46.9)	3.006	0.391
BSI (%)	6 (12.8)	9 (9.8)	10 (18.9)	7 (14.3)	2.468	0.481
Other BIs (%)	7 (14.9)	8 (8.7)	7 (13.2)	7 (14.3)	1.635	0.651

χ² value and P value represent overall comparison among the four groups. BIs: Bacterial infections; AD: Acute decompensation; ACLF: Acute-on-chronic liver failure; SBP: Spontaneous bacterial peritonitis; BSI: Bloodstream infection.
