Table 1. Relationship between age and Vestibular Function parameters.
Right and Left ear comparison shows the mean difference between right and left ears. Student’s t-tests were used for all comparisons with the exception of a one-way ANOVA for comparing vertical canal vHIT gain. The overall mean (SD) includes right and left ears combined. The right-most column shows the r and p-values obtained in the Pearson correlation between the overall mean and age for all vestibular outcomes.
