1. Error in Table

In original publication [1] there was a mistake in Table 1. The rows with the Mortality of 30 day and 90 day respectively should switch columns so that 10 (13) and 15 (19) patients died in the All Patients group, and 3 (12) and 4 (16) patients died in the Flow Cytometry Patient group. The corrected

2. Text Correction

We hereby state that there was an error in the original publication and a mistake was made in the text as below.

In the abstract, subsection Results, fifth row:

“The expression levels of intracellular tumor necrosis factor alpha (TNFα) and IL-1 receptor type 2 in leukocytes were higher (p < 0.001) as well as plasma levels of TNFα, IL-2, IL-6, IL-8, IL-10 (p < 0.001), interferon gamma (IFNγ) (p < 0.01), and granulocyte-macrophage colony-stimulating factor (GM-CSF) (p < 0.05)”.

The word higher in the sentence above should be lower. And then the whole sentence needs to be revised, suggestion below:

“The expression levels of intracellular tumor necrosis factor alpha (TNFα) and IL-1 receptor type 2 in leukocytes were lower (p < 0.001), and the plasma levels of TNFα, IL-2, IL-6, IL-8, IL-10 (p < 0.001), interferon gamma (IFNγ) (p < 0.01), and granulocyte-macrophage colony-stimulating factor (GM-CSF) (p < 0.05) were higher in patients with severe COVID-19 than in the control group”.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
