Fig. 6: Areal bone mineral density (aBMD) assessed by dual-energy X-ray absorptiometry (DXA) is associated with bone marrow fibrosis grade (MF grade).

a Association of MF grades with spinal and femoral aBMD assessed by DXA in myelofibrosis patients (n = 101). b Association of MF grades with radial and tibial total vBMD (Tt.vBMD) assessed by high-resolution peripheral quantitative computed tomography (HR-pQCT) in myelofibrosis patients (n = 80). c Association of fibrosis area to marrow area (Fb.Ar/Ma.Ar) with spinal and femoral aBMD (n = 35). d Association of fibrosis area to marrow area (Fb.Ar/Ma.Ar) with radial and tibial Tt.vBMD (n = 30). All data points and simple linear regression analyses including 95% confidence intervals are shown. Associations between the presented parameters were calculated using Spearman’s rank correlation (a–d). The correlation coefficient r with the corresponding exact p-value is shown above each graph. Numbers in bold indicate statistical significance (p < 0.05). Source data are provided as a Source Data file.
