Figure legends
Figure 1. Ct values when the RdRP gene (A) and Egene (B) were targeted by using nasopharyngeal swabs to detect
SARS-CoV-2 on the basis of the days after symptom onset
The Ct values between the severe and mild groups were compared with the
Wilcoxon rank sum test.
Figure 2. Ct values when the RdRP gene (A) and Egene (B) were targeted by using sputum specimens to detect SARS-CoV-2 on
the basis of the days after symptom onset
The Ct values between the severe and mild groups were compared with the
Wilcoxon rank sum test.
Figure 3. Ct values when the RdRP gene and E gene
were targeted to detect SARS-CoV-2 on the basis of the days after
symptom onset in all the patients
Figure 4. Chest radiograph scores according to the days after
symptom onset
The chest radiograph scores between the severe and mild groups were
compared with the Wilcoxon rank sum test.
