FIGURE 6.
For the perimodiolar electrode, changes in ECochG CM drops for 250-Hz are more strongly correlated with frequency-specific audiogram threshold shift at both 250- and 500-Hz compared to ECochG CM drops when using 500-Hz stimulus. (A) Moderately strong linear correlation between audiogram threshold shift at 250-Hz from preoperative to 1-month post-activation and largest ECochG CM drop for 250-Hz. (B) Moderately strong linear correlation between audiogram threshold shift at 250-Hz and largest ECochG CM drop for 500-Hz. (C) Moderately strong linear correlation between audiogram threshold shift at 500-Hz and largest ECochG CM drop for 250-Hz. (D) Weak linear correlation between audiogram threshold shift at 500-Hz and largest ECochG CM drop for 500-Hz.
