Clinical characteristics and classification using logistic regression with exhaustive feature selection and cross-validation of near-term DTI compared to near-term structural MRI findings, in VLBW preterm children who scored below one SD (< 1SD) versus equal to or greater than one SD (≥ 1SD) below mean BSID-III cognitive and motor score. MRI findings include presence of white matter abnormality (WMA), cerebellar signal abnormality, and cerebellar asymmetry.
