The Spearman rank correlations between predicted network strength and observed scores are presented here. For the MS-wmCPM internal sample, correlations are reported between predicted and observed WM scores. The “Network Model” indicates which model was applied to which “Sample” data using which “Network.”
Indicates permuted p* = p < 0.05, ** = p < 0.01.
MS, multiple sclerosis; MSE, mean squared error; MS-wmCPM = WM connectome-based predictive model derived in the internal sample of individuals with multiple sclerosis using linear regression and leave-one-out cross-validation; WM = Working Memory; wmCPM = WM connectome-based predictive model derived in healthy young adults by Avery et al. (2020).
