BackgroundDysbiosis of gut microbial community is associated with the pathogenesis of CD and may serve as a promising non-invasive diagnostic tool. We aimed to compare the performances of the microbial markers of different biological levels by conducting a multidimensional analysis on the microbial metagenomes of CD. MethodsWe collected fecal metagenomic datasets generated from eight cohorts that altogether include 870 CD patients and 548 healthy controls. The microbial alterations in CD patien...
