Association of subchondral bone marrow lesion localization with weight-bearing pain in people with knee osteoarthritis: data from the Osteoarthritis Initiative

Table 6 Associations between changes in BML scores and changes in weight-bearing pain

BML score changes	Pearson’s r	p	Β (95% CI)	p
Total score	0.13	0.002*	0.07 (0.00–0.13)	0.04*
Medial FT joint	0.16	< 0.001**	0.10 (0.02–0.18)	0.01*
Lateral FT joint	− 0.06	0.13	− 0.21 (− 0.53–0.11)	0.20
Medial PF joint	− 0.01	0.73	− 0.10(− 0.31–0.11)	0.34
Lateral PF joint	0.02	0.58	0.10 (− 0.09–0.30)	0.29
Subspinous region	0.10	0.01*	0.21 (− 0.03–0.45)	0.09

B_: Model for total BML score adjusted for sex, baseline weight-bearing pain, age, and BMI, total BML score, and change in non-weight-bearing pain. BML subscores in addition adjusted for BML at the other four joint compartments. *p < 0.05, ** p < 0.01
