Table 2 Results for one-way ANCOVA for groupwise comparisons of mean \(\chi\), PCS, DCS and R2*. ANCOVA with post-hoc Welch’s t-tests were carried out with Cohen’s d reflecting the effect size. FDR-corrected q-values are shown for both group-wise tests and post-hoc tests. Bold entries indicate significance at the q < 0.05 level
