Risk factors associated with the loss of cartilage volume on weight-bearing areas in knee osteoarthritis patients assessed by quantitative magnetic resonance imaging: a longitudinal study

Table 5 Parameters predicting medial central tibia cartilage volume loss at 24 months: stepwise forward multivariate regression

	Beta coefficient	Standard error of beta	P value
Severe meniscal extrusion	-0.33	0.09	0.0004
WOMAC pain (change)	-0.26	0.09	0.007
Bone hypersignal in the lateral compartment	-0.19	0.09	0.03
Severe lateral meniscal tear	0.21	0.09	0.02
WOMAC stiffness	-0.16	0.09	0.07

Correlations were done with baseline values unless otherwise indicated. Values were adjusted by factors listed in Table 3. WOMAC, Western Ontario and McMaster Universities Osteoarthritis Index.
