Flowchart of study inclusion for and exclusion from analysis for a) stroke studies and b) TBI studies.
Figure 2.
Key characteristics of TBI epidemiology and research as compared to stroke.
The data for TBI are presented as a ratio of the stroke data. TBI has a similar prevalence and higher incidence when compared to stroke, but total recruitment numbers and number of studies are significantly fewer than in stroke.
Figure 3.
Number of studies starting recruitment in each year for stroke and TBI.
Stroke has a greater increase in the number of studies starting recruitment annually as compared to TBI.
Figure 4.
Number of studies per enrolment interval.
The vast majority of both stroke (84%) and TBI (94%) studies recruit fewer than 1000 participants. NK = not known.

Figure depicts location of study recruitment.
The majority of both stroke (58%) and TBI (67%) studies are single centre. NK = not known.
