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.
