Correlation between osteophyte formation and OA severity.

Quadrants	TV			OV
	2	3	4	2	3	4
r	0.81	0.91	0.81	0.81	0.91	0.93
p	0.03	0.005	0.02	0.03	0.005	0.003

TV: Total volume of interest; OV: Osteophyte volume. The correlation coefficient, r, and p values are reported. p < 0.01 was considered significant.
