Linear regression analysis to test for correlation of the OsR and NR with FD parameters, MCR (%) (A and C) and pore density (1/mm2) (B and D). Linear regression analysis to test for correlation of the OsR and NR with FD parameters, MCR (%) (A and C) and pore density (1/mm2) (B and D). A and B, MCR (R2 = 0.0106) and pore density (R2 = 0.0157) were independent of the OsR. C and D, MCR (R2 = 0.0182) and pore density (R2 = 0.0055) were also independent of the NR. Corresponding β and P values are also provided. N. Paliwal et al. AJNR Am J Neuroradiol 2019;40:288-294 ©2019 by American Society of Neuroradiology
