Ipsilateral = ear ipsilateral to stimulation, Contralateral = ear contralateral to stimulation.

Order refers to the order in which subjects were enrolled (Patients are listed in order of z score for the contralateral side).

% Diff = the percentage of change in VARL score from baseline to the last day of active treatment. The z score is the standardized z score calculated from each % Diff distribution.

Class is classification of treatment outcome: R=treatment responder (negative z score following active stimulation for either ear, corresponding to at least a 33% decrease in VARL from baseline); NR=nonresponder (positive z score after active stimulation).

^*Subject was classified as NR because VARL changed from 2 to 1, which is not clinically relevant.
