Columns show the percentiles of the probability distribution of the mean EFR magnitudes for the difference between the two indicated noise exposure categories (the first category minus the second category). The mean contrast is indicated by the 50th percentile (.50), while the 90% confidence interval is indicated by the 5th and 95th percentiles.
