      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Simple individual randomization with random allocation with envelopes in 2 groups A and B . In this method, we selected a number of cards or letters as an intervention group and the same ‎number of cards for the control group, then the cards were merged. One card was taken out and its ‎allocation was registered and the card was returned to the other cards after leaving. Then the cards ‎are merged again and we remove another card. This process continues to reach a random sequence ‎according to sample size, Blinding description: This study is a double-blind clinical trial. In this study, patients consciously consented to take vitamin C and N-acetylcysteine supplements but did not know the type of group they were entering. The drug is prescribed by infectious and internal medicine physicians in charge of the project and is randomly given to one of these two groups; However, the intern in charge of the project, who is responsible for registering questionnaires and collecting data, also does not know about the patient group.</study_design>
