Regression coefficients (point estimates, standard errors and P-values) on the link scale between change in global network measures and clinical outcome. Log-transformed lesion volume is included as a nuisance regressor. In the case of NIHSS and FMa:=66-FM scores, quasi-Poisson regressions with a log-link are used; in the case of relative grip strength, a Gaussian regression with identity link is used. The first three columns (‘pooled model’) represent pooled estimates from joint two-stage regressions across the subacute and chronic stages. P-values 0.05 are marked in bold.

FM = Fugl-Meyer; NIHSS = National Institutes of Health Stroke Scale; rGS = relative grips strength; SE = standard error.
