Box and whisker plot of SPEV showing the median (horizontal line), interquartile range (limits of the box), outliers (o), and extreme cases (*) of the four types of caloric tests. Over all caloric tests, the median SPEV was 9.6 and 16 for EOG and VOG, respectively. The EOG measure for the same SPEV was greater suggesting greater sensitivity of the EOG technique
