Figure 1. Viral Load Rebound after Covid-19.
Shown are changes in the mean viral load among the study patients who received a course of nirmatrelvir–ritonavir or placebo within 5 days after the onset of symptoms of severe acute respiratory syndrome coronavirus 2 infection (Panel A). Also shown are data for patients with present or persistent viral load rebound in the two groups (Panel B). In Panel B, the lower limit of quantification of the reverse-transcriptase–polymerase-chain-reaction assay was 2 log10 copies per milliliter; the blue line indicates hospitalization of the patient.
