Localization patterns of hyperintense FLAIR lesions in prematurely born and term-born adults
| Localization | VP/VLBW | FT | p | ||||
|---|---|---|---|---|---|---|---|
| n | Median | IQR | n | Median | IQR | ||
| Periventricular | 24 | 2.0 | [1.0–4.0] | 7 | 1.0 | [1.0–2.0] | 0.053 |
| DWM | 33 | 4.0 | [2.0–6.5] | 16 | 1 | [1.0–2.0] | 0.004 |
| Subcortical | 35 | 3.0 | [1.0–9.0] | 49 | 2.0 | [1.0–5.0] | 0.447 |
Group differences of lesion numbers per localization were tested by Mann-Whitney U‑test. Cases without lesions in one of the three categories were not analyzed
DWM deep white matter, FT full-term, VP/VLBW very preterm and/or very low birthweight, IQR interquartile range
