Robustness: Number of abnormal voxels (n = 34).

<p>Note- Mean number of abnormal voxels (SD) detected by each analysis method from each group for each global metric (1) “All” - all abnormal white matter voxels across the whole brain, (2) “Low” - all white matter voxels where FA was significantly higher than normal and (3) “High” - all white matter voxels. Paired t-test was conducted for each global metric to compare numbers of abnormal voxels detected in mTBI patients using each of two reference groups (n = 20, n = 40).
