These analyses used the SCAT symptom survey, Standardised Assessment of Concussion, modified Balance Error Scoring System, modified Vestibular\/Ocular Motor Screening (mVOMS), Immediate Post-Concussion Assessment and Cognitive Testing, King-Devick, Clinical Reaction Time and numerous neuropsychological tests in concussed versus non-concussed individuals within 48 hours of injury.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Individual symptoms in the symptom survey demonstrated a variety of Cohen\u2019s d effect sizes, the largest being pressure in head (d=2.59), do not feel right (d=2.51) and headache (d=2.85). The largest effect sizes of the examinations were Symptom Severity Score (d=2.09) and mVOMS (d=3.41). The proposed mSIT is the sum of the 7-point Likert symptom scores for headache, pressure in head, do not feel right, sensitivity to light, dizziness and sensitivity to noise (range 0\u201336). The AUC\/sensitivity\/specificity of SCAT symptom severity index was 0.88\/85\u2009%\/76%, whereas mSIT was 0.94\/87\u2009%\/88%. The only concussion test\/examination which added utility to mSIT was mVOMS with an AUC\/sensitivity\/specificity of 0.94\/88\u2009%\/92%\u2009when used in combination. The proposed clinical cut-off score is \u22652 for mSIT and \u22652 for mVOMS. All other examinations in CARE were non-additive in acute concussion identification.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>For a shorter concussion evaluation, the 6-question mSIT is recommended, improving the AUC from 0.88 to 0.94 with 2% better sensitivity and 12% better specificity compared with the 22-item SCAT Symptom Severity Score. Adding mVOMS further marginally enhances these metrics and can be completed within 2\u20133\u2009min (mSIT Plus).<\/jats:p>\n
