Relation of M:L BMD Ratio Groups to the Prevalence of BMLs

Medial Meniscal Damage	M:L BMD Ratio Groups
Medial Meniscal Damage	1 (0.70 – 1.11)	2 (1.11 – 1.18)	3 (1.18 – 1.27)	4 (1.27 – 1.91)	p for trend
Adjusted Odds Ratio of Medial Meniscal Damage (95% CIs)	1.0 (reference)	1.9 (1.3 – 2.9)	2.4 (1.6 – 3.6)	8.9 (5.1 – 15.5)	p<0.0001

Odds Ratios are adjusted for age and sex.

Italicized results are meniscal damage prevalence measurements stratified by radiographic OA status
