^*Change from randomization to final hemodynamic measurement.

^†N/A due to missing mixed venous oxygen saturation observations.

Abbreviations: CO=cardiac output; CI=cardiac index; MVOS=mixed venous oxygen saturation; TFC=thoracic fluid content; PCWP=pulmonary capillary wedge pressure; SV=stroke volume; TPG=transpulmonary gradient; HR=heart rate; SVR=systemic vascular resistance.

The number of subjects who contributed observations for the various parameters ranges from 58 to 67.
