Table 3. Association between quadriceps measurements and knee alignment as determined by regression analyses adjusted for age and disease severity.

	B	R2
Quadriceps torque, Nm/kg	−0.001	0.066
VM/VL ratio	3.224	0.141

B: unstandardized regression coefficient. VM: vastus medialis; VL: vastus lateralis. *Significant difference, p < 0.05.
