(A) Respiratory system compliance (Crs) according to both the coronavirus disease (COVID-19) status and the recruitability. High recruitability denotes a recruitment-to-inflation ratio ≥0.5. Conversely, low recruitability denotes a recruitment-to-inflation ratio <0.5. No significant difference was found between any subgroup. COVID-19− denotes patients without COVID-19; COVID-19+ denotes those with COVID-19. (B) Crs plotted against the time since onset of COVID-19 symptoms. No correlation was found between the Crs and duration of symptoms. Red squares represent patients with a recruitment-to-inflation ratio ≥0.5, and blue circles represent patients with a recruitment-to-inflation ratio <0.5.
