Group-level strength selectivity analysis. (a) Strength selectivity in all tested frequency bands with a z threshold of 1 reveals significantly higher broadband and beta strength selectivity in good-outcome patients vs. poor-outcome patients. (b) A sweep across multiple z thresholds from 0 to 2 reveals significant outcome-dependent differences in strength selectivity for broadband (z = 1), beta band (z = 0.5 to z = 1.25) and low-gamma band (z = 1.75 to z = 2) networks (mean +/− standard error). Beta band strength selectivity distinguishes between good- and poor-outcome patients across the widest range of z thresholds (red box). *p < .05, Mann-Whitney U test.
