An increase in the severity ofCOVID-19 pneumonia was associated with higher median values of leukocytes (p< 0.001), neutrophils (p < 0.001), D-dimer (p = 0.005),aspartate aminotransferase (p = 0.010), serum urea (p = 0.009),lactate dehydrogenase (p < 0.001), myoglobin (p = 0.026), glucose (p< 0.001), procalcitonin (p = 0.022) and C-reactive protein (p <0.001), lower platelets count (p = 0.005), lower albumin (p < 0.001)and lower sodium (p = 0.03). Here, CRP is linked to pneumonia.
