Samples by body site.

Each row indicates a body site related to the human microbiome. The “Samples” column indicates the total number of samples categorized under each body site, and the “Countries” column indicates the number of unique countries with at least 1 sample in that category. Samples without a known country are included in the sample count, but not the country count. Body sites map directly to categories defined in the NCBI Taxonomy Browser; see S5 Table for a list of category IDs combined for each body site.每一行对应一个与人类微生物组相关的人体部位。其中，"样本（Samples）"列代表该人体部位分类下的总样本数，"国家（Countries）"列代表该分类下至少拥有1份样本的独特国家的数量。未标注确切来源国家的样本将被计入总样本数，但不会被纳入国家计数范畴。人体部位直接映射至NCBI分类学浏览器（NCBI Taxonomy Browser）中定义的分类类别；各人体部位合并后的分类ID列表详见附表S5。
