Multivariate logistic regression analysis regarding mortality

Variable	Odds ratio	95% Confidence interval	p value
Age	0.968	(0.928, 1.01)	0.132
Male gender	2.783	(0.76, 10.19)	0.122
In-hospital stay	1.098	(1.005, 1.201)	0.039
AKIN stage 2	0.19	(0.046, 0.787)	0.022
Minimal eGFR (mL/min)	1.015	(0.936, 1.1)	0.721
Peak CRP (mg/L)	0.994	(0.987, 1.001)	0.094
NT-proBNP (pg/mL)	1–1.456e-5	(1–7.137e-5, 1 + 4.224e-5)	0.615
ICU treatment (> 10 days)	0.013	(0, 0.35)	0.01
Diabetes (insulin-dependent)	0.179	(0.039, 0.83)	0.028
No pre-existing CKD	1.088	(0.285, 4.15)	0.902
No pre-existing CHF	1.621	(0.478, 5.492)	0.438
Bmi (mg/qm)	1.137	(1.023, 1.264)	0.017
No neoplasia	5.105	(1.221, 21,349)	0.026

Three variables were identified as positive predictors of survival: in-hospital-stay, BMI, and negative history of neoplasia; three variables however were negatively predictive: AKIN stage 2, ICU treatment for more than 10 days, and insulin-dependent diabetes
