At week 24 BW20 in ipsilateral AI has a higher rate of spectrally nonoverlapping binaural activation compared with contralateral AI (P < 0.01, χ²-test). CF misaligned sites in ipsilateral AI have higher rates of nonoverlap activation (P < 0.01, Fisher exact test). Relative to BW10, monaural activation rates have decreased, as expected. Convention same as in Table 2. N, count.
