The properties of degree distribution. (a) The cumulative degree distribution of the DPN with exponent γ = 2.65 (b) The cumulative in-degree distribution of the DPN with exponent γ in  = 2.32. (c) The cumulative out-degree distribution of the DPN with exponent γ out  = 2.95. (d) The positive correlation between the in- and out-degrees of diagnoses.
