2.3. Randomization and Blinding
Participants were randomly assigned in a 1:1 ratio to oral Favipiravir or placebo. The same pharmacological factory made the placebo and Favipiravir. The placebo was the same as Favipiravir in size, shape, and color. An independent staff packed Favipiravir and placebo in identical boxes and labeled them A or B. The random string was generated using “Randomization.Org” by the project manager. The participants, physicians, outcome evaluator, data analyzer, and the project manager were unaware of the treatment assignments.
