Fidelity of audiology and research appointments in the open-label extension. Audiology appointments were for clinical assessment and follow-up. Research appointments were restricted to outcome assessments. Fidelity is calculated relative to the end of the RCT phase (visit 6), with visit 10 at 36 weeks after initial device fitting. Mean across participants in days; standard deviation in brackets.
