In comparison, for patients without COVID-19, S100A12 expression was above 12.2 in one of the 10 non-ICU patients, and 12 of the 16 ICU patients (75%), while IFI27 expression was above 6.0 in none of the 10 non-ICU patients, and only 2 of the 16 ICU patients. This evidence concerns the gene S100A12 and COVID-19.
