ECD strength of HFS side vs. ECD strength of control side, paired t-test.

Comparison of the ratio of ECD strength according to each factor, Mann–Whitney test.

* ECD strength of N100m on the HFS side/ECD strength of N100m on the control side.

Abbreviations: AICA, anterior inferior cerebellar artery; ECD, equivalent current dipole; PICA, posterior inferior cerebellar artery; S.D., standard deviation.
