Patient subgroups, mean infarct sizes, and fiber ratios
| Group Outcome | n | Mean Infarct Size, mm2 | Fiber Ratio |
|---|---|---|---|
| I, “favorable”: MS=5 (maximum of 1 deficit) | 12 | 139.42 ± 57.77 | 1.14 |
| II, “moderate”: MS ≥ 4− (and maximum of 2 deficits) | 6 | 248.00 ± 161.04 | 0.55 |
| III, “unfavorable”: MS ≤ 3 (and further deficits) | 7 | 243.43 ± 98.02 | 1.05 |
Note:—Inclusion criteria for different subgroups (long-term outcome) are detailed in the first column. Group I had a motor score (MS) of 5 and a maximum of 1 neurologic deficit. Group II had at most 2 deficits and a minimum score of 4−. Group III had an MS ≤ 3 and further deficits. Fiber ratios were smaller for patients with lower MS, though confounders with higher amounts of ipsilateral voxels, partly due to high fractional anisotropy in acute stroke phases, were present in 3 of 7 cases in group III.
