Figure 2.

Bar graph with two panels compares VOR gain (Panel A) and prevalence of hypofunction (Panel B) across four groups: MD lesion, MD intact, IVN lesion, and IVN intact, broken down by conditions H, P, and A, with means, standard errors, numerical sample labels, and cutoff thresholds indicated.

Lesion vs. intact side—MD (n = 11, A–D) and IVN (n = 12, E–H). (A–D) MD group (n = 11, upper row); (E–H) IVN group (n = 12, lower row). Columns: (A,E) = FHIT H-canal correct answer rate (CA%); (B,F) = FHIT P-canal CA%; (C,G) = vHIT H-canal VOR gain; (D,H) = vHIT P-canal VOR gain. Filled circles = lesion side; open circles = intact side; bars = mean ± SD; dashed lines = cutoff (80% for FHIT; 0.8 for vHIT H-canal; 0.7 for vHIT P-canal). Brackets with p-values: Wilcoxon signed-rank test (lesion vs. intact). †: MD vs. IVN Mann–Whitney U test (lesion side).
