Number of abnormal LUS findings during hospital stay evaluation time points D1–D10 in all groups of patients: CD+ = patients with signs of cardiac dysfunction; CD−: patients with no signs of cardiac dysfunction; CD+ IMV = CD+ patients who required IMV; no-survivors = patients who died during their stay. All types of B-lines evaluated were grouped. The number of patients included is different for each time point (Table 2). *Statistical difference between groups (p < 0.05)
