Note. #indicates moderate or large and significant effect, with adequate Nfs; Nstudies = Total number of studies included in analysis, NTBI = total number of participants in traumatic brain injury (TBI) group, Ncontrol = total number of Control participants, mean dw = mean weighted effect size, SE = standard error, 95% CIs = 95% confidence intervals, Nfs = Fail safe N,%OL = percentage overlap between the distribution of scores for the TBI and Control groups, NS = nonsignificant. A significant Q indicates a heterogeneous distribution. Where Q statistics were sig, as indicated by *, a random-effects model was used to calculate d. FA = fractional anisotropy.
