  1. The partial correlations were computed with age and gender as the confounding covariates. *p < 0.05, corrected. γ value was calculated by Cp/mean(Cprand), λ value was calculated by Lp/mean(Lprand). The small-worldness value of σ was presented by γ/λ. Note there are more KT metrics exhibiting significant correlations to cognitive performances than DT metrics
