Table 2.

Olig2 cell density (cells/mm2) across the six boxes in periventricular leukomalacia (PVL) cases only.

Box PVL (n = 18) (cells/mm2)
1 138.7 ± 15.9
2 131.4 ± 15.6
3 128.5 ± 16.0
4 127.8 ± 17.0
5 123.5 ± 17.1
6 111.5 ± 17.0

The post-conceptional age-adjusted mean ± SEM of Olig2 cell density (cells/mm2) decreased significantly across the six boxes in PVL cases (P = 0.003). Box 1 indicates the area overlying the necrotic focus, whereas Box 6 is the most distant (6 mm). P < 0.05 is considered significant.
