Symptoms comparison between interventional vs observational groups. Box and whisker plots showing the median and range of days when COVID-19 symptoms were definitely better (A) and when symptoms resolved (B) between the interventional and observational groups. In the interventional group, all patients definitely felt better in either 2 or 3 days, narrowing the range. Outliers (each star denotes an outlier) occurred in the observational group with delayed symptom improvement in 2 patients and delayed resolution of symptoms in 4 patients. One of these patients developed PASC and remained symptomatic through the end of the study at day 180, widening the time to resolution range in the observational group.
