Table 2.

For three different time points as well as the longitudinal (acute DTI metrics predicting early or late chronic behavioral scores) analyses, the p-values from the regression analyses and the rho values from the partial correlation analyses (residual values obtained the multivariable linear and logistic models) are highlighted. For statistically significant associations, the area under the curve (AUC) values from the receiver operating characteristic (ROC) for the regression models and odds ratio (OR) (with 95% confidence interval in brackets) calculations for the logistic regression models are shown. Correlations that remained significant after false discovery rate analysis is presented in bold font.
