Table 3.

Ten statistical regression models were evaluated. Models 1-3 evaluated baseline MR findings. Models 4-10 evaluated changes in MR findings frombaseline to 48 months. All 10 models were adjusted for age, sex, and BMI. P-values were calculated using a likelihood ratio test comparing each model to a base model. The base model consisted of only age, sex, and BMI

Model number	Model	Variables	Number of variables added to base model	P value
1	Baseline meniscal findings	Anterior horn, posterior horn, and body of medial and lateral meniscus	6	0.110
2	Baseline cartilage findings	Cartilage of patella, trochlea, medial and lateral femoral condyles, medial and lateral tibia	6	0.028
3	Baseline bone marrow findings	Bone marrow of patella, trochlea, medial and lateral femoral condyles, medial and lateral tibia	6	0.226
4	Incident meniscal tear	Medial and lateral meniscus	2	<0.0001
5	Progressive meniscal tear	Medial and lateral meniscus	2	0.121
6	Incident cartilage lesion	Cartilage of patella, trochlea, medial and lateral femoral condyles, medial and lateral tibia	6	0.438
7	Progressive cartilage lesion	Cartilage of patella, trochlea, medial and lateral femoral condyles, medial and lateral tibia	6	<0.0001
8	Incident bone marrow lesion	Bone marrow of patella, trochlea, medial and lateral femoral condyles, medial and lateral tibia	6	0.034
9	Progressive bone marrow lesion	Bone marrow of patella, trochlea, medial and lateral femoral condyles, medial and lateral tibia	6	0.055
10	Incident effusion	Incident effusion	1	0.0003
