Hemoconcentration is a poor predictor of severity in acute pancreatitis

Table 1 Hemoconcentration at admission as a marker for severe acute pancreatitis (AP), necrotizing AP and organ failure

	Hemoconcentration	No hemoconcentration	Odds ratio ( 95%CI )	P value (χ2)
	(Hct≥44% M, Hct≥40% F)1	(Hct <44% M, Hct <40% F)
Severe AP (n = 336)
No	168	90	0.77	0.32
Yes	46	32	(0.4-1.3)
Necrotizing AP (n = 150)
No	55	41	1.17	0.64

Organ failure (n = 336)
