(A) The directed networks demonstrated small-world architectures over a wide range of sparsity. For the FDR threshold (sparsity = 7.44%): = 1.66, = 1.04; for the strongly connected (SC) threshold (sparsity = 13.07%): = 1.28, = 1.02. (B–D) The directed networks at these two sparsities (FDR threshold: 7.44% and SC threshold: 13.07%) showed high consistency on the nodal out-degree (r = 0.91, P = 4×10⁻³⁶) (B), in-degree (r = 0.87, P = 4×10⁻²⁹) (C) and out-in degree (r = 0.90, P = 3×10⁻³³) (D).
