Table 3 Distribution of medial periarticular bone mineral density (paBMD) changes among knees with medial tibia bone marrow lesion (BML) regression, progression, or no change ( n= 308)

From: Bone marrow lesion volume reduction is not associated with improvement of other periarticular bone measures: data from the Osteoarthritis Initiative

  Outcome: Medial paBMD change quartiles (min, max, gm/cm2)  
Predictor 1st Quartile 2nd Quartile 3rd Quartile 4th Quartile Proportional odds ratio
(-0.149, -0.033) (-0.032, -0.004) (-0.004, 0.018) (0.018, 0.168)
  n = 77 n = 77 n = 77 n = 77 (95% CI)
BML Regression (-8.44, -0.14 cm3) n = 76 16 (21%) 15 (20%) 22 (29%) 23 (30%) 1.72 (1.05 - 2.82)
No BML or no BML change (-0.13, 0.03 cm3) n = 156 45 (29%) 44 (28%) 36 (23%) 31 (20%) Reference
BML Progression (0.04, 6.77 cm3) n = 76 16 (21%) 18 (24%) 19 (25%) 23 (30%) 1.61 (0.98 - 2.65)
  1. Notes: paBMD, periarticular bone mineral density. Proportional odds ratio of greater quartile of medial paBMD is compared with the referent group.
