The area under the receiver operator characteristic (AUROC) curve was 92.2%. Known associations with oral pathogenic features, benefits-generated features, and functional features of CRC were confirmed by the model.Conclusions Our optimized prediction model was established using large-scale experimental population-based data and other sequence-based faecal microbial community data. This model can be used to identify high-risk groups and has the potential to become a novel screening method for CRC biomarkers due to its low 1-specificity (i.e. false-positive rate) and good stability.","study-name":"An optimized model for screening colorectal cancer established using large-scale experimental sequence-based faecal microbial community data","data-origination":"HARVESTED"},"relationships":{"geocoordinates":{"links":{"related":"https://www.ebi.ac.uk/metagenomics/api/v1/studies/MGYS00005190/geocoordinates?format=json"}},"biomes":{"links":{"related":"https://www.ebi.ac.uk/metagenomics/api/v1/studies/MGYS00005190/biomes?format=json"},"data":[{"type":"biomes","id":"root:Host-associated:Human:Digestive system:Large intestine:Fecal","links":{"self":"https://www.ebi.ac.uk/metagenomics/api/v1/biomes/root:Host-associated:Human:Digestive%20system:Large%20intestine:Fecal?format=json"}}]},"publications":{"links":{"related":"https://www.ebi.ac.uk/metagenomics/api/v1/studies/MGYS00005190/publications?format=json"}},"analyses":{"links":{"related":"https://www.ebi.ac.uk/metagenomics/api/v1/studies/MGYS00005190/analyses?format=json"}},"downloads":{"links":{"related":"https://www.ebi.ac.uk/metagenomics/api/v1/studies/MGYS00005190/downloads?format=json"}},"samples":{"links":{"related":"https://www.ebi.ac.uk/metagenomics/api/v1/studies/MGYS00005190/samples?format=json"}}},"links":{"self":"https://www.ebi.ac.uk/metagenomics/api/v1/studies/MGYS00005190?format=json"}}],"meta":{"pagination":{"page":1,"pages":1,"count":1}}}
