Fig. 1From: Nasopharyngeal viral load predicts hypoxemia and disease outcome in admitted COVID-19 patientsViral load is associated with minimal saturation values and age. The relationship between Ct values from the nucleocapsid gene, minimal saturation values and age (n = 170). Similar results were obtained with the Ct for the envelope gene.
