Classification of patients according to 25-point CT severity score.
A mild grade is of 0–7 points, a moderate grade is of 8–16 points, and an advanced grade is of 17–25 points. And collectively, as the cut-off value for severe cases identification was 7, the 252 patients in this study were classified into two groups, the mild COVID-19 group (174 patients) with a CT severity score from 0 to 7 points, and the severe COVID-19 group (78 patients) which includes [(moderate grade cases (58 patients) + advanced grade (20 patients)] with a CT severity score of more than 7 points.

CT scan chest with multi-planar and color-coded images.
(A) A 44 years old male patient presented with fever and cough. CT scan chest with multi-planar and color-coded images showed bilateral multi-focal patchy ground-glass opacities with a peripheral subpleural predominance (asterisk). CT severity score was 7. The patient exhibited a mild disease course. (B) A 30 years old male patient presented with fever, dyspnea, and cough. CT scan chest with multi-planar and color-coded images showed widespread bilateral central and peripheral confluent ground-glass opacities (asterisk). CT severity score was 21. The patient exhibited a severe disease course.
