Nevertheless, multilinear regression analysis of RT (change angle, average d′, and bias as predictors; see materials and methods ) revealed a more negative standardized regression coefficient for RT variation with bias as compared with d′, that approached significance (β b-LR = −0.082 [−0.21 0.05], β d′ = −0.019 [−0.069 0.071] – median [95% confidence interval]; P = 0.046, bootstrap test for difference of β-magnitudes).
