Summary of sensitivity and FPR of CAEP tests for different analysis methods
| Test Description | α | FPR | Stimulus | Sensitivity | |||
|---|---|---|---|---|---|---|---|
| Theoretical | Measured | Overall (≥ 0 dB SL) | 0 to 10 dB SL | >10 dB SL | |||
| Single HT2 test, single stimulus (Fig. 6A) | 0.05 | 5.0% | 4.5% | MF | 69.6% | 54.3% | 80.3% |
| 0.0% | HF | 53.7% | 42.5% | 60.3% | |||
| Initial or repeat HT2 tests, single stimulus (Fig. 6B) | 0.05 | 9.8% | 9.1% | MF | 83.9% | 69.6% | 93.9% |
| 0.0% | HF | 72.2% | 60.0% | 79.4% | |||
| Initial and repeat HT2 tests, either stimulus (Fig. 6B, black line) | 0.05 | 18.5% | 9.1% | Either | 92.6% | 81.3% | 97.4% |
| Initial or repeat HT2 tests, single stimulus (adjusted p value on both tests) | 0.025 | 4.9% | 0.0% | MF | 82.1% | 65.2% | 93.9% |
| 0.0% | HF | 66.7% | 60.0% | 70.6% | |||
| Initial or repeat HT2 tests, single stimulus (adjusted p value on second test) | 0.05 then 0.025 | 7.4% | 0.0% | MF | 82.1% | 65.2% | 93.9% |
| 0.0% | HF | 70.4% | 60.0% | 76.5% | |||
The theoretical FPR has been calculated based on the number of tests and α level, as described in the main text.
CAEP, cortical auditory evoked potential; FPR, false positive rate; HF, (mid-)high-frequency (stimulus); HT2, Hotellings T2; MF, mid-frequency (stimulus); SL, sensation level.
