*, denotes statistically significant differences between patients with and without supplemental oxygen. P-value of <0.05 is considered statistically significant. CRSmax, maximum COVID-19 Radiographic Score; CRPmax, maximum C-reactive protein; LDHmax, maximum lactate dehydrogenase; Lymphocyte countmin, minimum lymphycyte count.
