The effect of the lowest in-hospital albumin level on the clinical outcome of 1055 patients.

Variable	Hypoproteinemia group (n = 924)	Normal group (n = 131)	P univariate	P multivariate
The time without vasoactive drugs	3.6 (1.6–9.3)	2.3 (1.3–5.1)	< 0.01	< 0.01
The time without mechanical ventilation	2.3 (1.2–4.2)	2.0 (1.2–3.5)	0.17	< 0.01
ICU stay	6.0 (2.7–13.0)	3.5 (1.8–7.0)	< 0.01	0.55
Hospital stay	13.7 (7.1–24.1)	8.1 (5.3–12.3)	< 0.01	0.63

In multivariate regression analysis, the influences of factors (such as SAPSII score, septic shock, chronic kidney disease, diabetes, hemoglobin, platelets, serum albumin, the lowest in-hospital albumin level, albumin supplementation, use of vasoactive drugs, and mechanical ventilation) were excluded.
