Methods of the Special L·OVE of Coronavirus The Living OVerview of Evidence (L·OVE) builds upon the general methods of the L·OVE platform and incorporates the following new methods: All of the evidence organized in the L·OVE platform is retrieved in real-time from the Epistemonikos Database (See Epistemonikos Database methods here). The team maintaining the L·OVE platform devised a search strategy for COVID-19, and each of the individual PICO questions available, using the following approach: • Identification of terms relevant to the population and intervention/test/variable components of the search strategy, applying Word2vec technology to the corpus of documents available in Epistemonikos Database. • Discussion of terms with content and methods experts to identify relevant, irrelevant and missing terms. • Creation of a sensitive boolean strategy encompassing all the relevant terms • Iterative analysis of articles missed by the boolean strategy, and refinement of the strategy accordingly. coronavir* OR coronovirus* OR betacoronavir* OR "beta-coronavirus" OR "beta-coronaviruses" OR "corona virus" OR "virus corona" OR "corono virus" OR "virus corono" OR hcov* OR covid* OR "2019-ncov" OR cv19* OR "cv-19" OR "cv 19" OR "n-cov" OR ncov* OR (wuhan* and (virus OR viruses OR viral)) OR sars* OR sari OR "severe acute respiratory syndrome" OR mers* OR "middle east respiratory syndrome" OR "middle-east respiratory syndrome" OR "2019-ncovrelated" OR "cv-19-related" OR "n-cov-related" To complement the searches in the 10 sources routinely performed in Epistemonikos Database Clinical characteristics and diagnostic challenges of pediatric COVID-19: A systematic review and meta-analysis Collaborators of the European Society of Paediatric Radiology Cardiothoracic Imaging Taskforce COVID-19) in children: a systematic review of imaging findings Pediatric COVID-19: Systematic review of the literature Clinical Characteristics of Children With COVID-19: A Meta-Analysis.
