This table gives an overview of participant-related characteristics, including the number of male and female participants, age, handedness, and pre- and postseason scores according to the four composite scores (verbal memory, visual memory, visual motor speed, and reaction time) derived from the results of the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT). One female participant did not undergo neurocognitive assessment by the ImPACT.
