Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Patient recovery (Patient recovered: PCR negative for ARI of viral etiology and absence of clinical symptoms of ARI. Patient not recovered: PCR positive for ARI of viral etiology or presence of clinical symptoms of ARI). Measurement time: 3rd day, 8th day and 10th day after starting the treatment

Key secondary outcomes:

1.- Clinical response (disappearance of clinical respiratory symptoms). Measurement time: Daily during the patient's treatment time. 2.- Virological response (negative PCR for ARI of viral etiology). Measurement time: on the 8th and 11th day after starting treatment. 3.- Severity of the disease (Classification of the disease into mild, moderate, severe and critical stages). Measurement time: Daily during the patient's treatment time. 4. Post-treatment clinical response (absence of clinical respiratory symptoms since the previous evaluation). Measurement time: on day 28 (week 4), day 56 (week 8) and day 84 (week 12) after the treatment was completed. 5. Security variables (Detection of adverse events during the physical examination of the patient or referrals). Measurement time: Daily during the patient's treatment time
