Table 2 Bone mineral density values of all HR-pQCT analyzed sites

HR-pQCT Site	BMD
2nd MCP head (number of patients = 50). mg/cm³	302.6 ± 56.6
Layers around erosion (number of patients = 26). mg/cm³
VOI-1	393.8 ± 81.2
VOI-2	347.7 ± 91.7
VOI-3	321.8 ± 78.3
VOI-4	304.9 ± 79.0
Radius (number of patients = 49). g/cm³
Ct.vBMD	868.8 ± 64.4
Tb.vBMD	152.7 ± 40.3
