Left ears showed a trend towards significance (0.82 ± 0.09 vs. 0.67 ± 0.05; p = 0.14); however, these differences were more statistical artifacts than an indication of potential hearing loss.

Between the type of data being analyzed and the low number of participants per aircraft, the r-squared values were low, in spite of higher associations and significance or near significance.
For the ABR slow-rate results in the upper portion of Table 12 , only Wave I to III latency (significance in right ears; trend in the left) and Wave V amplitude (trends in both ears but almost significant in the left) had decreases in both ears.
However, the right ear latency data for the Wave I slow rate and Wave V fast rate indicated a possible trend toward hearing issues for flight line personnel working on F-15 aircraft based on the ABR tests. 3.10.
Meanwhile, in the right ears, the trend was the opposite, with the Wave V amplitudes and amplitude-to-latency ratios showing a slight trend of differences between controls and T-4 participants and no difference for Wave V fast-rate latency.
There was a strong trend for a greater fast-rate Wave V latency in the left ears of T-4 participants than controls, but the Wave V amplitudes and amplitude-to-latency ratios were not different.
