Summary of measurements obtained is shown for various measures of interstitial fibrosis, tubular atrophy, epithelial cell mass [EPCM, Epithel below], microvessel density (MVD), and microvessel area (MVA).

Stains applied include trichrome (Tri), periodic acid–Schiff (PAS), collagen III (Col) immunohistochemistry (IHC), cytokeratin (CK) IHC for EPCM, and CD34 IHC for the MVD and MVA. Measurements are either performed using morphometric or visual (Vis) methods. For fibrosis morphometry, a method employing trichrome minus the PAS measurement is used (T-P). For EPCM, the “Red” of the trichrome is also used (RedTri). The outer (Out) and inner (Inn) stripe (Stri) widths are also measured. (Std Dev = Standard Deviation).
