N1 CAEP occurrence as a function of age of implantation. A subset of children ages 6 years and older was analyzed. Age 6 years was used as a criterion for reasonable detectability of the N1 based on studies of normal hearing children. The red arrow indicates the age of cochlear implantation at which cluster analysis determined two separate age clusters (ages 2.02–6.58 years; ages 7.61–14.63 years) of subjects based on their implantation age and the presence of the N1. The vertical axis shows the number of children presenting with the N1 and the horizontal axis shows the age of implantation, divided into one-year increments.
