Descriptive characteristics of injury situation, sex, concussion history and sport participated in during the incidence of concussion. Severity characteristics for concussions reported within 48 hours of injury, including mean Post Concussion Symptoms Score severity and symptoms scores and 95% CIs are reported. Recovery characteristics, including mean difference score of non-sport- and sport-related concussions, as well as median and IQR for days to symptom resolution and RTP are also reported.
