Furthermore, when we compared the differences between tumor and mucin community membership and relative abundance using the classic Jaccard and Yue & Clayton (thetaYC) indices, we found that the two communities were not significantly different (P = 0.947, AMOVA using Jaccard indices; P = 0.83, AMOVA using thetaYC indices). The gene discussed is MUC5AC; the disease is neoplasm.
