  1. Student’s t test was used to compare the mean values of BAP, PINP, NTx, TRACP-5b, pentosidine, and homocysteine. p value indicates the significance of difference between participants with and without BMLs
  2. BAP bone-specific alkaline phosphatase, BML bone marrow lesion, NTx crosslinked N-telopeptide of type I collagen, PINP procollagen type I N-terminal propeptide, TRACP-5b tartrate-resistant acid phosphatase-5b, BML bone marrow lesion
