KDM1A and ganglioneuroma: Analysis of immunohistochemical staining of LSD1 revealed that there was a positive correlation between LSD1-positive staining score and the tubular pathology score (r = 0.702, P < 0.001), tubular atrophy (r = 0.673, P < 0.001), and interstitial fibrosis (r = 0.596, P < 0.001) in the HBV-GN group.
