A, Graphs referring to LUS exams performed on COVID‐19 patients; B, graphs referring to LUS exams performed on post‐COVID‐19 patients. On the top left of (A) and (B) the overall distributions of scores considering the four systems are shown, and, on the top right of (A) and (B), the level of agreement between systems 1, 2, and 3 with respect to system 4 is depicted. Each exam is represented by a beam of the polar plot. The score is indicated by the length of a beam. The longer the beam, the higher the score. For further details about the structure of agreement graphs see Smargiassi et al. ¹¹ On the bottom left of (A) and (B) the distributions of each score in the posterior areas (basal, middle, and apical) are shown, and, on the bottom right, the level of agreement between the 3 modified versions of system 4 (10 zones instead of 14: ie, all of the anterior and lateral areas together with apical posteriors, middle posteriors, or basal posteriors) with respect to system 4 is shown.
