Pattern of dynamic changes in the total CT score and CT image pattern of lung lesions from disease onset in patients with COVID‐19. The graph shows dynamic changes in mean total CT score (A), percentage of consolidation (C), and percentage of mixed pattern (E) between nonsurvivors (progressive deterioration pattern) and survivors (initial deterioration to peak level involvement followed by improvement pattern). Percentage of ground‐grass opacity (B) is persistent more than 50% both in nonsurvivors and survivors within 28 days from illness onset, while the percentage of crazy‐paving pattern (D) is persistently increased until days 10 to 13, followed by decreased and no observed on days 21 to 28 both in nonsurvivors and survivors.
