Univariate analysis of Ki-67 groups.
| Variable | Ki-67 | Wilcoxon–Mann–Whitney Test | ||||
|---|---|---|---|---|---|---|
| Low (<10%) | High (>10%) | U | Z | p | r | |
| MTE | 110.34 (28.03) | 79.99 (23.15) | 48 | 3.38 | <0.001 | 0.53 |
| FA | 0.24 (0.16) | 0.19 (0.06) | 86 | 2.31 | 0.020 | 0.36 |
| MD | 1.04 (0.47) | 1.22 (0.25) | 189 | 0.89 | 0.373 | 0.14 |
| AD | 1.29 (0.36) | 1.43 (0.30) | 175 | 0.47 | 0.649 | 0.07 |
| RD | 0.91 (0.53) | 1.10 (0.26) | 197 | 1.20 | 0.238 | 0.19 |
Values are expressed as medians and the interquartile range. MTE = mean tissue elasticity, FA = fractional anisotropy, MD = mean diffusivity, AD = axial diffusivity, and RD = radial diffusivity.
