The Huber and Kaiser have asked for clarification on drop-outs of participants over the course of the study and the statistical methods. From the original 23 cochlear implant candidates (CIC) in the control group, 9 participants received implants after 6 months and had to be excluded from the study. Ethically, when these candidates have an opportunity to receive an implant, their surgery cannot be delayed because of participation in a research project. Both CIC (n = 23, mean age (M) = 69.04 ± 12.35) and cochlear implant recipients (CIR) (n = 16, M = 61.75 ± 15.62 yr) completed baseline and 6 month assessments. Of the 16 CIR, 5 participants were unavailable for the 12-month assessment (as noted in Table 1) but still remained in the study.
