3.3 Analysis of outcome differences in the AHL1 subgroup (n = 26)
In the AHL1 subgroups, no specific frequency differed significantly with three outcomes (Figure 1C) or two outcomes (Figure 2C). Compared with the other unspecified etiologies, the retrocochlear etiology of hearing loss was found more often for successful users than for intermittent or failed users (p = 0.040)(Figure 3E). Compared with CNS or other unspecified causes, sudden hearing loss was found more often for successful users than for the other two outcome groups (p = 0.040)(Figure 3F). No significant discriminant function was found with three outcomes or two outcomes.
