Table 6 Correlation between chest CT severity score and laboratory data of the studied cases

From: Correlation between chest CT severity scoring system with oxygen saturation and laboratory inflammatory markers in adult patients with COVID-19 infection

Laboratory data Test CT severity score N = 305
Oxygen saturation R − 0.878**
  P < 0.001 HS
Absolute lymphocytic count R − 0.263
  P < 0.001 HS
D-dimer R 0.633**
  P < 0.001 HS
CRP R 0.714**
  P < 0.001 HS
Ferritin R 0.498**
  P < 0.001 HS
  1. ** means high significant
  2. This table reveals that CT severity score, blood oxygen saturation level, and absolute lymphocytic count of examined cases had a high statistically significant negative correlation, but D-dimer, CRP, and ferritin had a statistically significant positive correlation
