Methods:
In our study, we extracted the published articles systematically from
PubMed, Google Scholar, and EMBASE, using terms “COVID-19”,
“SARS-CoV-2”, “nCoV-19” in combination with “treatment,”
“therapeutic agents,” “randomized control trials,” “pharmacology,”
and “drug therapy” to find articles in which treatment and therapeutic
agents against COVID 19 were discussed. All these articles were reviewed
by the authors, and related articles were screened out. Out of 6288
articles searched, two authors independently excluded the articles not
related to our exclusion criteria unanimously, then the articles for
which they dissented whether those should be included or not, the third
author was the tiebreaker, and then the screening was completed without
bias. We included only clinical trial reports, in vitro studies, and
review articles.
