Small retrospective database analysis of 37 late stage patients hospitalized in an intensive care center in China, not finding a significant difference in viral shedding. Pateints were all in serious condition. There was only one death however the group is not specified. Confounding by indication is likely.
time to viral-, 40.0% higher, relative time 1.40, p = 0.06, treatment 18, control 19.
