Fig. 4. Asymmetry ratios for BCV Fz oVEMPs of all 17 patients with unilateral vestibular loss (filled circles) plotted as a function of age. Also shown are ARs for BCV Fz oVEMPs of 50 healthy subjects (empty circles). Means and two-tailed 95% CI for mean are shown within the square and the boxplots for the medians, quartiles and ranges are shown outside the square. All patients have an asymmetry ratio greater than any normal subject tested.
