Table 1.

Items studied in the chest X- ray analysis of patients with Covid 19. (From: https://doi.org/10.1038/s41598-020-66895)

Each chest radiograph was analyzed for the following items
  1. Hilar shadows (Normal - prominent/accentuated - Enlarged), Hazy or well defined.

  2. Central linear lung vascular markings (normal - Prominent/accentuated – Diminished).

  3. Fine vascular linear shadowing (basal and parahilar) (normal – Prominent/increased - diminished).

  4. Beaded appearance of fine vascularity (+ve or -ve).

  5. Interstitial linear lung shadowing (normal - Increased).

  6. Septal lines (Kerley’s A – Kerley’s B – interlacing lines each +ve or -ve).

  7. Fine interstitial honeycomb pattern (no, basal, parahilar, upper zones, all zones).

  8. Tiny (small) ill-defined soft tissue patchy veiling (fine alveolar shadowing) (-ve, one, few (less than 7), multiple, numerous).

  9. Tiny (Small) ill-defined alveolar shadowing distribution (1 lobe, 2 lobes, more than 2 lobes).

  10. Tiny (Small) ill-defined alveolar shadowing site (peripheral lung zone – central lung zone – both zones).

  11. Lung consolidation (one patch – few patches - Multiple patches).

  12. Distribution of consolidation (1 lobe - 2 lobes - more than two lobes).

  13. Site of consolidations (peripheral - central - both).

  14. Thick linear lung shadowing (No – one – Few – Multiple).

  15. site of thick linear shadowing (peripheral - central – both).

  16. Distribution of thick linear shadowing (one lobe – two lobes – More than two lobes).

  17. Bronchiectasis changes (No – few – Multiple).

  18. Site of bronchiectasis changes (central – peripheral – Both).

  19. distribution Bronchiectasis changes (one lobe – two lobes – More than two lobes).

  20. Segmental Lung collapse (No – few – Multiple).

  21. Site of segmental lung collapse (central, peripheral, both).

  22. Distribution segmental Lung collapse distribution (one lobe, two lobes, More than two lobes).

  23. Nodular lung shadowing (No - one - Few – Multiple).

  24. Size of nodular shadows (military, micronodular, nodular, macronodular, massive shadows).

  25. Site of nodular lung shadowing Central – Peripheral - both).

  26. Distribution of nodular lung shadowing (one lobe- two lobes – more than two lobes).

  27. Pleural effusion (No – Unilateral, Bilateral).

  28. Severity of pleural effusion (Minimal – Mild – Moderate – Severe).

  29. Scoring of each Pt (0 – 1 – 2 – 3 – 4 – 5 – 6 – 7 – 8 – 9 – 10).

  30. Scoring of the follow up radiographs (1w,2w,3w).
