Table 1. Mean patient characteristics of bimodal and unilateral subjects.
| Variable | Bimodal | Unilateral | p | ||
|---|---|---|---|---|---|
| (n = 26) | (n = 22) | ||||
| Sex (male/female,n) | 11/15 | 15/7 | 0.089 | ||
| Age (years) | 63.8 | (2.7) | 67.3 | (3.0) | 0.384 |

| Duration of deafness pre-implantation (years) | 38.8 | (3.2) | 32.1 | (3.5) | 0.164 |
| Residual hearing pre-implantation (PTA, dB HL) | 92.1 | (2.6) | 100.2 | (4.3) | 0.103 |
| Residual hearing (PTA, dB HL) | 96.6 | (2.7) | 107.6 | (3.8) | 0.020* |
| CNC FITTED (%) | 70.4 | (4.0) | 62.6 | (6.7) | 0.323 |

Mean (standard error) per group and significance of difference between groups (*p<0.05) based on Fisher's exact test for the variable 'sex' and independent-samples Student T-tests for other variables. CI = cochlear implant, HA = hearing aid, FITTED = referring to CIHA in case of bimodal and CI in case of unilateral, CNC = consonant-nucleus-consonant maximum phoneme score across 55-65-75 dB SPL in quiet free-field, PTA = pure-tone average across 0.5, 1 and 2kHz under headphones in the unaided non-implanted ear.
