a Pearson correlations between joint space volume and joint space in the metacarpal bone imaged by high-resolution peripheral quantitative computed tomography (HR-pQCT) in the anti-TNFα treatment group. b Pearson correlation between changes in erosion volume and joint space in the metacarpal bone imaged by HR-pQCT in the anti-TNFα treatment group. c Pearson correlation between changes in trabecular bone mineral density (BMD), and changes in erosion volume and joint space in the metacarpal bone imaged by HR-pQCT in the anti-TNFα treatment group
