Distribution of medial-to-lateral periarticular bone mineral density (M:L paBMD) changes among knees with medial tibia bone marrow lesion (BML) regression, progression, or no change (n= 308)
Outcome: Medial:lateral paBMD ratio change quartiles (min, max)
Predictor 1st Quartile 2nd Quartile 3rd Quartile 4th Quartile Proportional odds ratio
(-0.119, -0.021) (-0.021, 0.000) (0.000, 0.022) (0.022, 0.410)
n= 77 n= 77 n= 77 n= 77 (95% CI)
BML Regression (-8.44, -0.14 cm3) n = 76 14 (18%) 18 (24%) 25 (33%) 19 (25%) 1.64 (1.00 – 2.69)
No BML or no BML change (-0.13, 0.03 cm3) n = 156 47 (30%) 45 (29%) 30 (19%) 34 (22%) Reference
BML Progression (0.04, 6.77 cm3) n = 76 16 (21%) 14 (18%) 22 (29%) 24 (32%) 1.85 (1.12 – 3.04)

Notes: paBMD, periarticular bone mineral density. Proportional odds ratio of greater quartile of medial paBMD is compared with the referent group.
