Table 1. Median number of accepted and shared epochs for Neuroscan and EPOC by condition and tone type.
Median (inter-quartile range) number of accepted epochs for the Neuroscan and EPOC systems and total number of epochs shared (i.e. accepted for both systems) between systems in each condition (passive and active) for each tone type (standard, deviant, and total). Wilcoxon Signed Rank Tests (Z) were used to test the difference between systems.
