Comparison of general and laboratory data between two groups
Of the 69 patients with pneumonia included in this study, 31 cases were SARS-CoV-2 positive and 38 were SARS-CoV-2 negative. The indicators between two groups were compared in table 1 . WBC (P< 0.001), LYM% (P < 0.001) and PLT (P< 0.001) in SARS-CoV-2 positive pneumonia group decreased significantly compared to those in common pneumonia group. In contrast, CRP (P = 0.027) and Hb (P < 0.001) in SARS-CoV-2 positive pneumonia group increased significantly compared to those in common pneumonia group (Table 1 ). No significant change in NE% was seen between two groups (Table 1 ).
