Comparing The Efficacy of Anti-Infectious Drugs For The Treatment of Mild To Severe COVID-19 Patients: A Protocol For A Systematic Review And Network Meta-Analysis of Randomized Clinical Trials.

Abstract

Background: COVID-19 is a viral infection spreading at a great speed and has quickly caused an extensive burden to individuals, families, countries, and the world. No intervention has yet been proven highly effective for the treatment of COVID-19. Different drugs were being evaluated and reported through randomized clinical trials, and more are currently under trial. This review aimed to compare the efficacy of anti-infectious drugs with a comparator of the standard of care or placebo in patients with COVID-19.Methods: Two independent review authors will extract data and assess a risk of bias using RoB2. Randomized controlled trials (RCT) that evaluate single and/or combined antiviral drugs recommended by WHO latest guideline for the treatment of COVID-19 will be included. We will search for Pub Med, the Cochrane Center for Clinical Trial database (CENTRAL), clinicaltrials.gov, etc. databases for articles published in the English language between December 2019 to April 2021. We will follow the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) involving Network Meta-analysis guidelines to design and report of the results. The primary endpoints will be time to clinical recovery and time to RNA negativity. The certainty of evidence will be evaluated using the GRADE extension of NMA. Data analysis will be performed using the frequentist NMA approach with the netmeta package implemented in R.Discussion: This review will reveal the best antiviral drug treatment for covid-19 and show the hierarchy of those drugs.Systematic review registration: The protocol was registered on PROSPERO with ID number CRD42021230919
