Comparison of the measurements of lenticulostriate arteries between CADASIL patients and healthy controls.
| Category | Patients with CADASIL (n = 46) | Healthy controls (n = 46) | t (z) | 95% CI (p25, p75) | P |
|---|---|---|---|---|---|
| Age (years)a | 43.26 ± 9.45 | 41.13 ± 10.26 | 1.036 | −1.955, 6.215 | 0.303 |
| Sex (male/female)c | 24/22 | 24/22 | – | – | 1.000 |
| LSA stems (number)b | 6.00 (6.00, 7.00) | 7.00 (6.50, 7.50) | −1.617 | 5.500, 8.000 | 0.106 |
| LSA branches (number)a | 10.72 ± 2.85 | 12.22 ± 2.70 | −2.591 | −2.650, −0.350 | 0.011* |
| Proportion of discontinuous LSAsb | 7.29 (4.17, 13.27) | 0.00 (0.00, 7.84) | −1.991 | 0.000, 15.846 | 0.047* |
| Length of LSAs (mm)a | 54.95 ± 6.85 | 55.56 ± 7.41 | −0.412 | −3.568, 2.343 | 0.682 |
LSAs, lenticulostriate arteries; Age, number of LSA branches and length of LSAs are presented as mean ± SD. Number of LSA stems and proportion of discontinuous LSAs are presented as median with 95% CI.
*
Significant difference.
a
Independent two samples t-test, and 95% CI of the difference is shown.
b
Mann-Whitney U-test, and p25–p75 of the transformation rank is shown.
c
Chi-square test.
