Fig. 7From: Histopathology of the broad class of carbon nanotubes and nanofibers used or produced in U.S. facilities in a murine modelHierarchical clustering analysis (HCA) and principal component analysis (PCA) of different CNT/F materials and bronchi/bronchiolar histopathology outcomes (A) and alveolar histopathology outcomes (B). For the PC, distance between two materials reflects the proximity in outcomes between themBack to article page
