Results from the mt function on the “Enterotypes” dataset.

The original “Enterotypes” dataset [91] (included in phyloseq) with OTU-wise testing of enterotype groups. Tests are a permutation-adjusted F-test using the Family-Wise Error Rate (FWER) as correction for multiple inferences (“adj-p” column). Not surprisingly, Prevotella and Bacteroides top the list, as they were major components of the “Enterotypes” classification described in the original article [91].

原始的“肠型”（Enterotypes）数据集[91]（已收录于phyloseq包）中，针对肠型群组开展了操作分类单元（Operational Taxonomic Unit，OTU）水平的检验。本次检验采用经置换校正的F检验，以家族错误率（Family-Wise Error Rate，FWER）作为多重推断的校正方式，校正后的P值对应结果列标注为"adj-p"。不出所料，普雷沃菌属（Prevotella）与拟杆菌属（Bacteroides）位居该检验结果列表的首位，二者正是原始文献[91]中所描述的“肠型”分类体系的核心组成成分。
