| Parameter | LMM factor type | Estimate | SD | t | P |
|---|---|---|---|---|---|
| Intercept | − 21 | 7.4 | 2.8 | 0.021 | |
| CI + HA | Fixed factor | − 1.3 | 0.48 | 2.8 | 0.0081 |
| N | Fixed factor | + 6.5 | 0.50 | 13 | < 10−6 |
| HAprior | Fixed factor | + 0.73 | 1.6 | 0.45 | 0.67 |
| SRTHA | Fixed co-variate | + 0.16 | 0.094 | 1.7 | 0.10 |
| PTA125–500 | Fixed co-variate | + 0.13 | 0.079 | 1.6 | 0.14 |
| Age | Fixed co-variate | + 0.10 | 0.070 | 1.5 | 0.17 |
CI + HA: bimodal hearing (parameter estimate is 0 for CI only); N: babble noise (0 for steady-state noise); SRTHA: SRT with only HA; PTA125–500: average pure-tune audiometric threshold across 125, 250, and 500 Hz; LMM: linear mixed model
