The overview of gut microbiota in new-onset RA patients and HCs. A The sequencing depth of the gut microbiota. The curve of each sample was nearly smooth, indicating that there was sufficient sequencing information from these samples in the RA and HCs. B The number of feature data in RA and HCs. C The β diversity analysis evaluated by principal coordinate analysis (PCoA) score showed that the composition of gut microbiota was significantly different between RA and HCs. D The relative abundance of gut microbiota at the phylum level in RA and HCs. E The relative abundance of gut microbiota at the genus level in RA and HCs. (RA: rheumatoid arthritis; HCs: healthy controls)
