Figure 2c: — Chest x-ray scoring system. A score of 0-4 was assigned to each lung depending on the extent of involvement by consolidation or GGO (0 = no involvement; 1 = <25%; 2 = 25-50%; 3 = 50-75%; 4 = >75% involvement). The scores for each lung were summed to produce the final severity score. Examples of chest x-ray severity scoring in patients with COVD-19 (Days from symptom onset; R lung score + L lung score = total score): (A) Day 12; 1 + 0 = 1. (B) Day 5; 2 + 1 = 3. (C) Day 3; 1 + 3 = 4. (D) Day 10; 4 + 3 = 7.
