Figure 4. PCA of 1H-NMR spectral data for albumin-treated patients on Day 7 compared to baseline samples taken before the first albumin or placebo treatment.

Figure 4

Samples were color coded green for baseline, blue for placebo and black for albumin on Day 7. Results showed that 3 days after last albumin treatment, metabolic differences showed a trend in patients receiving albumin. Corresponding plot for patients receiving placebo showed no separation. Data were analyzed with mean centered.
