Extended Data Fig. 4: SARS-CoV-2 variation in severe or critical and mild cases of COVID-19.
From: Viral and host factors related to the clinical outcome of COVID-19

Variations of SARS-CoV-2 from patients with differing severity of COVID-19 are plotted. Blue, nonsynonymous mutations; grey, synonymous mutations. Red bar, severe or critical COVID-19; purple bar, mild COVID-19. Two-sided Fisher’s exact test; 95% confidence intervals and odds ratios are shown. P values are shown on the right.
