The connectivity of PPI networks constructed by DEGs at the ith round of rectification under different parameters. The PPI connectivity is the ratio of the number of nodes in the largest connected component of the PPI network to the number of DEGs generated at the ith round of rectification. The x-axis represents the number of initial gene list of the Two-way rectification, while the y-axis represents the connnectivity of PPI network constructed by DEGs obtained at the ith round of rectification. a shows the connectivity results of each method when m=0.05, n ∈ (1, 100). b depicts the connectivity results of each method when m=0.1 and n ∈ (1, 100)
