D-dimer correlates with neutrophil-to-lymphocyte ratio (NLR) and IL-6 in COVID-19-infected patients. (A) D-dimer level correlates with NLR in all 69 COVID-19 patients (Pearson correlation, R = 0.5195, p < 0.0001). (B) D-dimer level correlates with IL-6 level in the serum of all 69 COVID-19 patients (Spearman correlation, R = 0.543, p < 0.0001). (C) Comparison of D-dimer levels in mild, moderate, and severe groups (p = 0.0002). (D) Comparison of NLR in mild, moderate, and severe groups (p < 0.001). *p < 0.05.
