Table 3 The correlation among disc height index, histological score, total NP GAGs and T1ρ values (Sperman rank correlation coefficient, rho)

From: In vivo experimental intervertebral disc degeneration induced by bleomycin in the rhesus monkey

  % DHI Histological score Total NP GAGs
T1ρ values of NP 0.601 -0.761 0.740
  P < 0.0001 P < 0.0001 P < 0.0001
T1ρ values of AF 0.630 -0.729 0.582
  P < 0.0001 P = 0.0003 P = 0.02
  1. NP = nucleus pulposus; AF = annulus fibrosus; % DHI = change in disc height index.
  2. GAGs = glycosaminoglycans.
