Edge number distribution of bootstrapped NI and REC networks, r = 1 to 0. a NI-CNs edge number boxplot from bootstrapping analysis at different r-values, at r = 1 to 0 at decrements of 0.1. b NI-CNs edge number boxplot from bootstrapping analysis at different r-values, at r = 0.3 to 0.2 at decrements of 0.01. c REC-CNs edge number boxplot from bootstrapping analysis at different r-values, at r = 1 to 0 at decrements of 0.1. d REC-CNs edge number boxplot from bootstrapping analysis at different r-values, at r = 0.5 to 0.4 at decrements of 0.01. In the boxplots, centerlines represent the median; box limits represent upper and lower quartiles; whiskers represent 1.5 × interquartile range. Bootstrapping was run 100 times with 80% of the samples allowing replacement. Grey vertical lines separate correlation coefficients, red dashed vertical lines represent proposed correlation coefficient threshold interval
