Additional file 1 of Integration of metabolic and inflammatory mediator profiles as a potential prognostic approach for septic shock in the intensive care unit

Three-dimensional PCA score scatter plots. Three-dimensional PCA score scatter plots obtained for 37 septic shock patients (red) and 20 ICU controls (green) based on the (A) metabolic data and (B) cytokine/chemokine data. The groups are well clustered along the axes of the three principal components. One septic shock sample is placed outside the sphere that describes the 95% confidence interval of the Hotelling’s T-squared distribution.
