| Variables | B | Constant | P value | EXP (B) | Sensitivity | Specificity |
| SD | 1.822 | −1.368 | 0.017 | 6.182 | 78.3 | 33.9 |
| CV | 0.037 | −1.071 | 0.040 | 1.038 | 81.9 | 27.4 |
| Relative size SD | 3.983 | −1.142 | 0.035 | 53.684 | 80.7 | 27.4 |
| Relative size CV | 0.039 | −1.136 | 0.033 | 1.040 | 80.7 | 27.4 |
SD calculated as the SD of the relative diameter of all the components of CBAN in an individual, and CV calculated as 100×SD divided by the average relative size of all the components of CBAN in an individual; significant at the p≤0.05.
CBAN, cerebral basal arterial network; CV, coefficient of variation.
