Joint space analysis parameter descriptions and precision values

Parameter	Units	SDD (RMSCV%)	Description
JSV	[mm³]	12.2 (3.5%)	Joint space volume; direct voxel-based measure of the volume of the intra-articular joint space
JSW	[mm]	0.11 (2.1%)	Joint space width; mean of local 3D widths across the joint space
JSW.SD	[mm]	0.07 (10.4%)	Joint space width distribution; standard deviation of local 3D widths across the joint space
JSW.MIN	[mm]	0.37 (12.5%)	Minimal joint space width; Minimal absolute 3D width across the joint space
JSW.MAX	[mm]	0.12 (2.2%)	Maximal joint space width; Maximum absolute 3D width across the joint space
JSW.AS	[ ]	0.92 (13.9%)	Joint space width asymmetry; ratio of the maximal to minimal joint space widths
