Correlations between the OARSI score and the Micro-CT quantitative bone parameters at 14 weeks. (a) BV/TV, (b) DA, (c) SMI, (d) TbPf, (e) TbSp, (f) TbTh, (g) TbN. Significant negative correlations were identified between OARSI scores and BV/TV, TbTh and TbN, and significant positive correlations were identified between OARSI scores and TbSp, TbPf, SMI and DA at 14 weeks. P values are indicated on b where statistically significant. The symbols represent the different specimens (● = Sham group, ▲ = PAM-L group, □ = ACLT group).
