| Age (in years) (mean ± SD) | 22.0 ± 1.4 | 20.2 ± 4.5 | 0.135 | |
| Handedness (right/left/ambidextrous) | 13/3/1 | 15/1/0 | 0.364 | |
| ImPACT score (preseason testing) (mean ± SD) | Verbal memory | 81.8 ± 9.5 | 81.2 ± 14.2 | 0.188 |

| Reaction time | 0.5 ± 0.04 | 0.6 ± 0.1 | 0.180 | |
| ImPACT score (postseason testing) (mean ± SD) | Verbal memory | 82.1 ± 13.0 | 78.6 ± 12.2 | 0.426 |
| Visual memory | 91.2 ± 7.0 | 92.5 ± 6.9 | 0.830 | |
| Visual motor speed | 47.3 ± 5.2 | 43.6 ± 5.4 | 0.597 | |

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). Results are shown as absolute numbers or mean ± standard deviation (SD). One female participant did not undergo neurocognitive assessment by the ImPACT. The only statistically significant finding was that females had a lower preseason visual memory score compared to males (p = 0.012).
