Table 4 Six-week mortality risk after AVH stratified by MELD score and blood transfusion requirement in the first 24 h after bleeding presentation

	MELD <18 (n = 159)	MELD ⩾18 (n = 49)
Blood transfusion <4 units PRBCs†	(n = 99) *	7.4 (2.4–23.5) p<0.001 (n = 26)
Blood transfusion ⩾4 units PRBCs†	3.4 (1.0–11.6) p = 0.06 (n = 60)	11.3 (3.9–33.0) p<0.001 (n = 23)

*HRs (95% CI) presented are relative to patients with MELD <18 and blood transfusion <4 units of PRBCs.
PRBCs were 250 ml per unit.
AVH, acute variceal haemorrhage; MELD, Model for End-stage Liver Disease; PRBCs, packed red blood cells.
