There are various inflammatory markers, such as the neutrophil/lymphocyte ratio (NLR), derived NLR (d-NLR), platelet/lymphocyte ratio (PLR), lymphocyte/monocyte ratio (LMR), C-reactive protein/lymphocyte ratio (CLR), systemic immune inflammation index (SII), C-reactive protein (CRP)-to-albumin ratio (CAR), high-sensitivity CAR (hsCAR), CRP-to-prealbumin ratio (CPAR), aggregate index of systemic inflammation (AISI), and prognostic nutritional index (PNI), for risk-stratifying and prognosticating COVID-19 severity and mortality [6,7]. This evidence concerns the gene ALB and COVID-19.
