Table 3 Multivariate logistic regression analysis of independent prognostic factors

Independent variable	Adjusted OR	95%CI	P value
APACHE II score ≥ 17	5.82	2.38-14.22	< 0.001
Infected necrosis confirmed	4.16	1.76-9.84	0.001
Drainage timing > 72 hours from diagnosis	3.74	1.58-8.86	0.003
CTSI ≥ 8	3.28	1.38-7.80	0.007
Organ failure ≥ 2 systems	3.06	1.23-7.62	0.016
CRP ≥ 300 mg/L at drainage	2.89	1.18-7.07	0.020
Collection volume ≥ 400 mL	2.54	1.06-6.08	0.036

Area under the curve of multivariate model = 0.892 (95% confidence interval: 0.837-0.947); Hosmer-Lemeshow goodness-of-fit P = 0.418. OR: Odds ratio; CI: Confidence interval; APACHE: Acute Physiology and Chronic Health Evaluation; CRP: C-reactive protein; CTSI: Computed tomography severity index.
