Cohort demographics: including the total number of patients, and the reported distribution by gender (with number of females and their percentage in the brackets). For the following statistics, the reported number of patients with the mean and standard deviation are provided in brackets: word score recognition (WRS), with CI and HA, pure tone average (PTA), and years of severe to profound deafness (YRS-D) for the implanted and contralateral ears. All individuals in this study were implanted between 2003 and 2018.
