Fig. 2.

Tract-based spatial statistics comparing the brain white matter skeletons at term equivalent age of babies exposed in utero to magnesium sulphate or placebo.

Footnote: A group-specific template underlies each axial (top four rows) coronal (middle four rows) and sagittal (bottom four rows) slices, with the white matter tract skeleton shown in green. Regions where the magnesium sulphate group (n = 60) had a significantly higher diffusion metric than the placebo group (n = 49) are shown in red-yellow (family-wise error corrected, P < 0•05), while regions where the magnesium sulphate group had significantly lower measures than the placebo group are in blue.(For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
