P values statistically significant are in bold font (p value ≤ 0.05). No signs of ILD corresponding to CT score = 0 and LUS score = 0. Signs of ILD corresponding to CT score = 1–25 and LUS score = 1–36. Mild ILD corresponding to CT score = 1–5 and LUS score = 1–7. Moderate ILD corresponding to CT score = 6–12 and LUS score = 8–18. Severe ILD corresponding to CT score 13–25 and LUS score 19–36. *No ILD is defined as CT score = 0. †ILD is defined as CT score ≥1.
