LNR and NMR at admission in hospitalized patients with severe Covid-19. (A) LNR showed a significant fourfold decrease in non-survivors as compared to survivors. LNR resulted of dividing the total lymphocyte count by the total neutrophil count. (B) NMR exhibited a significant twofold increase in non-survivors with respect to survivors. NMR resulted of dividing the total neutrophil count by the total monocyte count. Normality of data distribution was estimated by the Shapiro–Wilk test. The unpaired Student’s t-test was used to compare LNR and MNR between survivors and non-survivors, and data are presented as mean ± standard deviation. Differences were considered significant when p < 0.05. LNR, Lymphocyte-to-neutrophil ratio; NMR, neutrophil-to-monocyte ratio.
