| Auditory | Uncomfortable loudness level for 2 kHz (audiogram) | 1.19 |
| Loudness recruitment for 4 kHz (loudness scaling), | ||
| log-transformed Hearing threshold level for 4 kHz (loudness scaling) | ||
| Self-reports | Familial hearing loss | |
| Sudden hearing loss | ||
| Subjective hearing problems in quiet | 5.99 | |
| Subjective hearing problems in noise | ||
| Hearing loss detected | ||
| Cognitive | Verbal intelligence | 1.51 |

| Grouping | Grouping variable (Bisgaard) | 2.09 |
| Total R2 = 69.26% | ||
Shown are all selected predictors in the stepwise regression approach with cross-validation in a thematically summarized and ordered sequence.
R2 = adjusted coefficient of determination.
ΔR2 = change in the amount of R2 in % by adding the respective predictor(s) reflecting the proportion of explained variance accounted for as the respective predictor(s) is/are added to the regression model.
