The algorithm used to integrate the computed features and determine a classification was pre-established in a separate study, prior to validation in the B-AHEAD II study. The Ahead 100 device provides one of two potential classifications of the patient's recorded EEG data: 1. "May correspond to brain electrical activity consistent with no structural brain injury visible on head CT in patients presenting as a mild traumatic brain injury, within 24 hours of injury." or, 2. "Corresponds to brain electrical activity that may be present in both patients with or without a structural brain injury visible on head CT.
