Webfigure 1:

Principal component analysis based on the 245 differentially regulated
genes comparing post-TX AKI and PGF allografts. The first three principal
components (PC) were plotted, capturing 85% of the variance in the dataset. Acute
kidney injury allografts (grey spheres) and allografts with primary kidney function
(black spheres) form two distinct clusters.
