It is presented in table 2 of the interventional procedures overview. Other relevant literature is in the appendix of the overview.
3.2 The specialist advisers and the committee considered the key efficacy outcomes to be: quality of life and helical-mastoid distance.
3.3 The specialist advisers and the committee considered the key safety outcomes to be: skin erosion over implants and infection.
