The use of penalised regression methods and an event-to-variable ratio greater than 100 reduce the risk of overfitting.4546 The use of parameters commonly available at first assessment increases its clinical applicability, avoiding the requirement for markers often only available after a patient has been admitted to a critical care facility.447 Of course a model developed in a specific dataset should describe that dataset best. However, by including comparisons with pre-existing models, reassurance is provided that equivalent performance cannot be delivered with a simple tool already in use.","tracks":[{"project":"LitCovid-PubTator","denotations":[{"id":"401","span":{"begin":391,"end":398},"obj":"Species"},{"id":"402","span":{"begin":7,"end":16},"obj":"Disease"},{"id":"403","span":{"begin":74,"end":82},"obj":"Disease"}],"attributes":[{"id":"A401","pred":"tao:has_database_id","subj":"401","obj":"Tax:9606"},{"id":"A402","pred":"tao:has_database_id","subj":"402","obj":"MESH:D003643"},{"id":"A403","pred":"tao:has_database_id","subj":"403","obj":"MESH:C000657245"},{"subj":"401","pred":"source","obj":"LitCovid-PubTator"},{"subj":"402","pred":"source","obj":"LitCovid-PubTator"},{"subj":"403","pred":"source","obj":"LitCovid-PubTator"}],"namespaces":[{"prefix":"Tax","uri":"https://www.ncbi.nlm.nih.gov/taxonomy/"},{"prefix":"MESH","uri":"https://id.nlm.nih.gov/mesh/"},{"prefix":"Gene","uri":"https://www.ncbi.nlm.nih.gov/gene/"},{"prefix":"CVCL","uri":"https://web.expasy.org/cellosaurus/CVCL_"}]},{"project":"LitCovid-sentences","denotations":[{"id":"T180","span":{"begin":0,"end":101},"obj":"Sentence"},{"id":"T181","span":{"begin":102,"end":533},"obj":"Sentence"},{"id":"T182","span":{"begin":534,"end":700},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T180","pred":"source","obj":"LitCovid-sentences"},{"subj":"T181","pred":"source","obj":"LitCovid-sentences"},{"subj":"T182","pred":"source","obj":"LitCovid-sentences"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"LitCovid-PubTator","color":"#93ecec","default":true},{"id":"LitCovid-sentences","color":"#ecd293"}]}]}}
