TBI, traumatic brain injury; FSE, Functional Status Examination; GOSE, Glasgow Outcome Scale Extended.

^ap < 0.001, ^*p ≤ 0.01 paired Wilcoxon signed rank test comparing change from time 1 to time 2 post-injury on the FSE.

^bp < 0.001 paired Wilcoxon signed rank test comparing change from time 1 to time 2 post injury on the GOSE.

^cp < 0.001 Paired Wilcoxon signed rank test comparing whether there is more change on one measure compared with the other.
