Panel of COVID-19 phenotypes: systematic review protocol

Abstract

\n Background The pandemic caused by the SARS-CoV-2 virus, called coronavirus disease 2019 (COVID-19), had an unexpected impact on much of the world, especially Brazil. People diagnosed with the virus manifest different levels of respiratory symptoms, ranging from mild to severe, and may need mechanical ventilation support. The interaction different factors lead to the development of a spectrum of time-related diseases in different phenotypes. Methods This review will consider observational studies published from December 2019 to July 2021, without language restrictions. Studies involving human subjects, adult participants (18 years and older), with subjects who have received a COVID-19 diagnosis using the reverse transcriptase polymerase chain reaction (RT-PCR) test as a reference for the detection of the SARS- CoV-2 virus, according to World Health Organization (WHO) guidance. The databases to be searched will include PubMed/MEDLINE, EMBASE, and CINAHL. The grey literature will also be searched for published research and unpublished studies, using Google Scholar. wo reviewers will independently screen all citations, full-text articles and abstract data. Potential conflicts will be resolved through discussion. Findings will be reported using a narrative synthesis of the results will be carried out around the prevalence, severity of the disease, mortality and risk among the different phenotypes of COVID-19. The I 2 statistic will be used to examine the heterogeneity between the studies, if possible, the meta-analysis will be conducted using the RStudio® statistical software package, and the data will be displayed using forest graphics. Discussion This review will disclose a panel of the different manifestations of the disease COVID-19, and to identify the real risk factor for the most serious phenotypes. Systematic review registration This protocol has been registered within the International Prospective Register of Systematic Reviews (PROSPERO)(CRD42020211439)
