Table 1: Demographic and assessment measures in each TBI group.
The “Test” column shows the p value from a statistical test of differences between groups. This p value is variously derived from a Chi-square test (Gender, # with PTSD diagnosis, # on medications), a one-way ANOVA (Age, fMRI data retained, % fMRI data lost, PCL-5, FCES), or a two-sample t-test between the Mild and Moderate groups (# TBIs, Time since last TBI).
