The topological characteristics of fungi-bacteria co-occurrence/co-exclusion networks. A, B The overall co-occurrence network in healthy and dandruff scalps, respectively. Each node shows one taxa of bacteria or fungi. The size of the node corresponds to the log-transformed degree of the microbiota. The thickness of the edges corresponds to the Spearman’s r coefficient (CCREPE). The color of the edges corresponds to the positive (> 0.5) (red) or negative (< -0.5) (green) relationship or weak correlation (-0.5 ≤ r ≤ 0.5) (gray). The length of the edges has no meaning. C Differences in Spearman’s r values between healthy and dandruff scalps at the overall (left), positive (center) and negative (right) levels (****: P < 0.0001, Wilcoxon test). D Differences in the degree or betweenness of co-occurrence network between healthy and dandruff scalp microbiota (**: P ≤ 0.01, ****: P < 0.0001, Wilcoxon test)
