The certainty of evidence was categorized into 4 levels ranging from very low to high. Within the GRADE framework, evidence from randomized controlled trials (RCTs) starts as high-certainty evidence and observational studies start out as low-certainty evidence, but can be rated down for the following reasons: risk of bias, inconsistency, indirectness, imprecision, and publication bias. Additionally, evidence from well-conducted observational studies start as low-certainty evidence, but can be rated up for large effects or dose–response.14","divisions":[{"label":"title","span":{"begin":0,"end":21}}],"tracks":[{"project":"2_test","denotations":[{"id":"32407808-23517554-43469241","span":{"begin":695,"end":697},"obj":"23517554"}],"attributes":[{"subj":"32407808-23517554-43469241","pred":"source","obj":"2_test"}]},{"project":"LitCovid-sentences","denotations":[{"id":"T96","span":{"begin":0,"end":21},"obj":"Sentence"},{"id":"T97","span":{"begin":22,"end":152},"obj":"Sentence"},{"id":"T98","span":{"begin":153,"end":239},"obj":"Sentence"},{"id":"T99","span":{"begin":240,"end":541},"obj":"Sentence"},{"id":"T100","span":{"begin":542,"end":697},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"T96","pred":"source","obj":"LitCovid-sentences"},{"subj":"T97","pred":"source","obj":"LitCovid-sentences"},{"subj":"T98","pred":"source","obj":"LitCovid-sentences"},{"subj":"T99","pred":"source","obj":"LitCovid-sentences"},{"subj":"T100","pred":"source","obj":"LitCovid-sentences"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"2_test","color":"#93a7ec","default":true},{"id":"LitCovid-sentences","color":"#c1ec93"}]}]}}
