As expected, the percentage of interstitial fibrosis and tubular atrophy (IFTA), as quantified in the renal cortex by the nephropathologist (data not shown), did not correlate with TGF-β1 (r = 0.129; p = 0.250) and CTGF (r = 0.156; p = 0.163), but showed a weak correlation with VEGF-A (r = 0.221; p = 0.048). This evidence concerns the gene CCN2 and Atrophy.
