Trial Outcomes & Findings for Screening for Autism Spectrum Disorders Using Auditory Brainstem Responses (NCT NCT03971578)

NCT ID: NCT03971578

Last Updated: 2023-08-14

Results Overview

Auditory Brainstem Response (ABR) peak V latency measurement for the five stimulation rates used in the study. The latency is the time, measured in ms, from the onset of the stimulus to the generation of the response peak component. ABR peak V is the most prominent response peak component in humans.
