Although our results did not show an association between survival and high levels of IL-6, IL-10, and TNF-α, the survival curves of severe COVID-19 patients were similar to those of critical COVID-19 patients in regard to high IL-10 levels; elevated IL-10 levels could be an early warning sign of low survival in patients with pneumonia and COVID-19. Here, IL10 is linked to susceptibility to pneumonia measurement.
