Statistical analyses of network measures and data plotting were carried out in MATLAB. For local network measures at a single graph density threshold, one way analysis of variance (ANOVA) was used with pre-scan manipulations as independent variables (p values were adjusted using a false discovery rate correction method). For global network measures at 9 different graph density thresholds we used a repeated measures ANOVA. Where appropriate, Tukey–Kramer tests were used for post hoc multiple comparisons (p < 0.05).
