Table 2. Summary of Pearson r calculations for each pairwise correlation between baseline and postexposure ABR thresholds of the 100 HMDP strains after excluding strains with baseline thresholds >40 dB to control for ceiling effect.
| Postexposure Threshold | Baseline Threshold | ||||
|---|---|---|---|---|---|
| 8 kHz | 12 kHz | 16 kHz | 24 kHz | 32 kHz | |
| 8 kHz | −0.13 | 0.01 | −0.09 | 0 | 0.05 |
| 12 kHz | −0.16 | 0.02 | −0.02 | −0.14 | −0.17 |
| 16 kHz | 0 | 0.15 | 0.08 | −0.07 | −0.06 |
| 24 kHz | −0.02 | 0.06 | 0.23 | 0.21 | 0.11 |
| 32 kHz | 0.13 | 0.23 | 0.23 | 0.19 | 0.19 |
The 4 kHz frequency was completely excluded as no strains had baseline thresholds <40 dB.
