n−3 pups had altered microbiomes.

16S ribosomal RNA genes in cecal stool samples as percent of total yield. Pups from indicated breeder diets were weaned to LF diet either in cages with their littermates. Each column represents one mouse. The column order of mice mirrors the presentation in Figure 2a. LF, Low Fat; n−3, omega-3. Results are representative of 2 independent experiments. Significance determined by t test (phyla) or ANOVA with Bonferroni’s correction (genera): * = p value <0.05, ** = <0.01, *** = <0.001, – = not significant. The results from the Low Fat group shown in this table are a subset of what was previously reported in reference 13. The remaining data is novel.

本数据集为盲肠粪便样本中16S核糖体RNA（16S ribosomal RNA）基因占总扩增产物的百分比数据。来自指定繁育日粮组的幼崽，均与其同窝幼崽共处同一笼盒中，断奶后转换为低脂（LF）日粮。表格每一列对应一只小鼠，小鼠的列序与图2a中的展示顺序一致。其中LF即低脂（Low Fat），n−3即Omega-3。本结果为2次独立重复实验的代表性数据。显著性检验采用t检验（针对菌门水平）或方差分析（ANOVA）结合Bonferroni校正（针对菌属水平）：*表示p值<0.05，**表示p值<0.01，***表示p值<0.001，–表示无显著性差异。本表中低脂组的实验结果为此前文献13报道数据的子集，其余数据均为首次公开的原创数据。
