Notes	Dates of study: September 2017 to September 2019 Funding sources: "Grant support and financial disclosure ‐  NIL" Declarations of interest: "Authors declared no conflict of interest" We contacted the trial authors in March 2021 to ask for more information the prospective trial registration status. The trial authors replied "a clinical protocol was designed before conducting the study that was presented to the institutional review committee. But the clinical trial was not registered except with the local hospital body and after reviewing they gave us the ethical permission and approval for conducting study." Not included in 2021 update because of lack of response from trial authors regarding our trustworthiness criteria (trial published since 2010 without prospective registration)
