简要总结

Constipation is a heterogeneous and multifactorial disease, influenced by a number of different genetic and environmental factors. By applying the standard two-stage GWAS strategy to design and carry out a metagenome-wide association study (MGWAS) to find the relationship between gut microbiota and constipation, to identify disease-associated metagenomic markers.

详细描述

This study is a two-stage case-control metagenome-wide association study (MGWAS) based on deep next-generation shotgun sequencing of DNA extracted from the stool samples from a total of 50 Chinese constipation patients and healthy controls.
