Table 6. Percentage of concussed athletes with self-reported symptom resolution within 1 day of testing classified as impaired Per RCI criteria as compared to non-injured controls.

Concussed

Sx- within 1 day of assessment Control Net gain (hits – FP)
ANAM
 1+ decline 44.4 27.9 16.5
 2+ decline 22.2 11.0 11.2
Axon
 1+ decline 52.6 24.4 28.2
 2+ decline 5.3 6.0 −0.7
ImPACT
 1+ decline 56.3 37.2 19.1
 2+ decline 21.9 5.9 16.0

Note. FP = False positives. Asymptomatic concussed group aggregates all follow-up time points, selecting any subject who self-reported symptom resolution within 1 day of any follow-up exam. Control data represent a weighted average of the false positive rates observed at each time point, weighted to match the percentage of 24-hr, day 8, and day 15 time points used in the concussed athlete column. “1+ decline” (and “2+ decline”) indicate the percentage of subjects with 1 or more (and 2 or more) significant declines from baseline across each test's set of RCIs.
