Table 3.

Crude and adjusted relative risk (RR) for incident or enlarging bone marrow lesion(s) (BML) in the same compartment as meniscal pathology. The analyses are stratified by ipsilateral cartilage status at baseline^*.

	Cartilage lesion at baseline		No cartilage lesion at baseline
	Incident or enlarging BML†		Incident or enlarging BML
Medial meniscus pathology	Yes	No	Yes	No
Yes	190	425	18	108
No	49	247	22	283
Crude RR (95% CI)	1.8	(1.4, 2.4)	1.9	(1.0, 3.4)
Adjusted RR (95% CI)§	1.6	(1.2, 2.1)	2.0	(1.1, 3.6)
Lateral meniscus pathology	Yes	No	Yes	No
Yes	64	119	8	34
No	48	401	17	650
Crude RR (95% CI)	2.8	(1.9, 3.9)	7.6	(3.5, 16.5)
Adjusted RR (95% CI)§	2.5	(1.7, 3.7)	7.9	(3.7, 17.1)

Numbers are n if not otherwise stated, 95% CI = 95% confidence interval.

^*Missing value for medial compartment for 2 knees and lateral compartment for 1 knee.

^†Missing value for 2 knees for the lateral compartment.

^§Poisson regression (using generalized estimating equations) adjusted for age, sex, body mass index, physical activity level, and mechanical axis at baseline.
