The averages for each group are shown, and within parentheses the standard deviation and number of subjects who completed self-report assessments are listed. Using the Wilcoxon rank-sum tests, the significances between the non-blast and blast groups were calculated as an uncorrected p-value under p column. The pFWE is the Bonferroni corrected p value for all 18 tests. The final column shows the Cohen's d effect size between the non-blast and blast groups. Of all successfully imaged subjects, only those who accurately submitted and fully completed their self-report assessments were included in this table.
Legend: SD, standard deviation; n, number of subjects; FWE, family-wise error; d, Cohen's d effect size.
