| 5 | TMRLF | –1.8 | 0.6 | –2.8 | <.01 | .88 |
| Model AD type-II | ||||||
| n/a | (Intercept) | –18.7 | 3.9 | –4.7 | <.0001 | – |

Note. The priority was established based on the accumulated adjusted R2 > .01. Columns show the predictor name, the estimate, standard deviation (SE), t value, and probability of a significant contribution (p). HTLHF = hearing threshold levels for high frequency; HTLLF = hearing threshold levels averaged for low frequency; TMR = temporal masking release; TiNLF = tone-in-noise detection threshold at 500 Hz.
