TL;DR: Proposed models for covid-19 are poorly reported, at high risk of bias, and their reported performance is probably optimistic, according to a review of published and preprint reports.

TL;DR: Assessment of the diagnostic accuracy of point‐of‐care antigen and molecular‐based tests to determine if a person presenting in the community or in primary or secondary care has current SARS‐CoV‐2 infection found no studies at low risk of bias for all quality domains and concerns about applicability of results across all studies.
Journal ArticleDOI

TL;DR: To assess the diagnostic accuracy of antibody tests to determine if a person presenting in the community or in primary or secondary care has SARS-CoV-2 infection, or has previously had SARS, and the accuracy of antibodies for use in seroprevalence surveys is assessed.
Journal ArticleDOI
Signs and symptoms to determine if a patient presenting in primary care or hospital outpatient settings has COVID-19 disease.

TL;DR: The diagnostic accuracy of signs and symptoms is assessed to determine if a person presenting in primary care or to hospital outpatient settings, such as the emergency department or dedicated COVID‐19 clinics, has CO VID‐19 disease or COVID19 pneumonia.
Journal ArticleDOI
Search Filters for Finding Prognostic and Diagnostic Prediction Studies in Medline to Enhance Systematic Reviews
Geert-Jan Geersing,Walter Bouwmeester,Peter Zuithoff,René Spijker,Mariska M.G. Leeflang,Karel G.M. Moons +5 more
TL;DR: Explorative prediction research is difficult to find in Medline, using any of the currently available search filters, yet application of either the Ingui filter or the Haynes broad filter results in a very low number of missed clinical prediction model studies.
