Table 2. Outcomes of the leave-one-variable-out and leave-one-test-out analyses to evaluate the dependency of the SOM on specific inputs.
DVA = dynamic visual acuity; SOT = sensory organization test; V-HIT = video head impulse test; General = sex/age/time since concussive incident/sport type; SVV = subjective visual vertical; VEMPs = cervical and ocular vestibular-evoked myogenic potential; mSPV = maximal speed of the slow phase velocity.
