Plasma proteins differing between healthy controls and CKD. (a) illustrates the proteins found to be significantly different in the plasma of the stage 3 or 4 CKD patients as compared to the healthy controls. (b) shows the proteins found to be significantly different between the post-transplant patients with stage 3 or 4 CKD as compared to the healthy controls. Considering the large number of proteins detected by this assay, we only included those with any differences between the CKD subjects and the post-transplant subjects as compared to the healthy controls. The heat map was created via Morpheus, https://software.broadinstitute.org/morpheus.
