Heatmap showing correlation between respiratory conditions and lung ultrasound patterns. Dendrogram shows hierarchical clustering of respiratory conditions and lung ultrasound. For example, with respect to lung ultrasound pattern, CPE and ARDS appear to be similar conditions. To attenuate the effect of very prevalent conditions on coloring, such as atelectasis and posterior consolidations, the contingency data was first log-transformed and then normalized by the maximum cell value. ‘A’ profile’ represents an A-profile without lungsliding. ARDS: acute respiratory distress syndrome; CPE: cardiogenic pulmonary edema
