FIG. 1.

(A) Presents scatter box plots representing the total pre-examination symptom (SX) burden for each group (HC, healthy controls; NM, University of New Mexico Hospital Emergency Department patients; CH, The Children's Hospital of Philadelphia Minds Matter Concussion Program patients). The dashed line indicates the 95th percentile for pre-examination symptoms in HC. Symptom provocation (Prov/positive symptom change = Δ Pos SX) and symptom variability (Var/change in symptom = Δ SX; C) following a non-neurosensory task (DDFS, double dorsiflexion foot stretch) are presented in B and C, respectively. D and E present scatter plots depicting the relationship between the number of days post-injury and pre-examination symptoms experienced by the NM and CH groups.
