Figure 4 Principle component analysis matrix loading by components. Graphic representation of pattern matrix of principal component analysis into three components/factors (factor 1: Inflammatory/hematological components; factor 2: Metabolic/renal/inflammatory components; factor 3: Electrolyte/age).
