a 16S rRNA amplicon sequencing results of the main OTUs at the genus level. The microbiota indicated large variations among individuals. The non-survivor ARDS group presented fewer bacterial genera compared with the survivor and control groups. b Microbial community structures of the ARDS patients and controls using principle coordinates analysis. UniFrac distances were calculated after constructing the phylogenetic tree. Each dot and percentage of axes represent one sample and contribution rate, respectively. c Comparison of alpha diversity and Shannon diversity index indicating the bacterial diversity within one sample between ARDS patients and controls. Alpha diversities of the ARDS patients and non-surviving ARDS patients were significantly lower than those of the controls (*P < 0.05). ARDS, acute respiratory distress syndrome; OTU, operational taxonomic units
