aIncludes IP joint of the thumb. *P < 0.05 compared with radius/ulna, **P < 0.01 compared with radius/ulna, ***P < 0.001 compared with radius/ulna. All P refer to Tukey's post hoc test. Data are expressed as a mean (standard deviation) percentage of sites per patient to account for the different number of joints at each site. CT, computed tomography; NBF, new bone formation. |
