  1. The data are given as “mean (standard deviation, SD)”, or as “count (percentage)” when indicated. For peripheral oxygen saturation (SpO2) and systolic pulmonary artery pressure, the data are provided as a function of the saturation level: normoxemia (SpO2 ≥ 95%), mild hypoxemia (90% > SpO2 ≥ 80%), and profound hypoxemia (80% > SpO2 ≥ 65%).
  2. TTE transthoracic echocardiography.
