Threshold for statistical significance using Wilcoxon signed rank test was set at P<0.05. Left, left-ear stimulation; Right, right-ear stimulation; Healthy, healthy-ear stimulation; Affected, affected-ear stimulation; Initial, initial MEG exam; 1 m, 1 month after initial exam (fixed stage); a, amplitude of N100m dipole moment (Q/nAm); l, latency of N100m dipole moment (ms); m, mean; sd, standard deviation; P1, significance of difference between pooled responses of contralateral vs. ipsilateral hemispheres on monaural stimulation to both ears in controls and patients, respectively; P2, significance of difference between pooled responses of hemispheres ipsilateral to vs. opposite to the healthy ears on monaural stimulation to both intact and affected ears of patients; P3, significance of difference between hemispheric responses on a subset level according to ear of stimulation (left-ear stimulation and right-ear stimulation respectively in controls, healthy-ear stimulation and affected-ear stimulation respectively in patients).
