Significant association between degree of astrogliosis and number of normal and pathological mitochondria in astrocytic endfoot processes of REF and iNPH patients. a There was a significant negative Pearson correlation between percentage GFAP IR, measured by immunohistochemistry, and number of normal mitochondria in astrocytic endfoot processes (R = − 0.48, P = 0.009). b There was a positive correlation between degree of astrogliosis and number of pathological mitochondria in astrocytic endfoot processes (R = 0.42; P = 0.026)
