Extended Data Fig. 9: Comparison of viral load between COVID-19 patients that develop critical versus non-critical disease.

Viral load at the day 1–3 time interval of hospital admission of COVID-19 patients that eventually develop critical versus non-critical disease. Data are presented as scatter plots with dots showing individual patient measurements, columns median values and error bars range. N = 8 for non-critically ill and n = 9 for critically ill COVID-19 patients. Statistical significance between the two groups was determined by a two tailed Mann–Whitney U test for non-parametric comparisons. n.s.: Not significant.
