To compare values between groups, the ANOVA or Student's t test was used.
EBL values between groups were compared using a Mann-Whitney U test; P <.05 as statistically significant.
Differences of CGRP values between groups were analysed with the Kruskal-Wallis H test.
Comparisons of values between groups were made by Mann–Whitney U test as appropriate.
Also, the addition of healthy controls is necessary to compare values between groups in further studies.
Comparing the mean values between groups, the t-test was used.
P values between groups were calculated using repeated measures two-way analysis of variance (ANOVA, interaction term).
There was no significant effect of body weight on the measured MBFi values between groups (ANOVA p = 0.08).
Student's t test was performed to find specific p values between groups found to have statistically significant differences.
Differences in the variances of corresponding values between groups were calculated using Bartlett's test.
No additional group differences in the percent change in ADC values between groups were found to be significant.
