Comparison of the intracellular MLKL levels between the clinical conditions showed a significant increase in the intracellular expression of MLKL in the C19wSepsis cohort compared to Sepsis Alone (> 6-fold increase, **p=0.0012), but not when compared to the C19NoSepsis cohort (p>0.05). Here, MLKL is linked to Sepsis.
