Results of logistic regression analysis relating presence of aneurysms to CV and SD

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.
