Table 5 Analysis of the interobserver agreement of CXR assessments of radiographs. The table presents the weighted κ and ICC values for the overall population as well as for individual exam types (PA vs AP) and the patient’s clinical condition as expressed using MEWS scale: Group A (MEWS 0–1), Group B (MEWS 2–3), and Group C (MEWS ≥4).
