Mean fractional anisotropy in infants with normal and adverse neurologic outcomes. Mean fractional anisotropy in infants with normal and adverse neurologic outcomes. Boxplots represent the distribution of individual subject values in groups with normal fidgety movements and normal BSID-III scores, aberrant fidgety movements and normal BSID-III scores, and aberrant fidgety movements and adverse neurodevelopmental outcome as measured by BSID-III at 24 months of age. The cognitive subscale was measured in the splenium of the corpus callosum. The motor subscale was measured in the cerebellar peduncle. The asterisk indicates P < .05 on ANOVA, Tukey post hoc comparisons. C. Peyton et al. AJNR Am J Neuroradiol 2017;38:162-169 ©2017 by American Society of Neuroradiology
