  1. In norepinephrine and dobutamine cases, absolute mean differences are presented. These were calculated as absolute results from increases and decreases in catecholamine dose
  2. NE norepinephrine, VE/PLR volume expansion/passive leg raising, DBT dobutamine, CFI cardiac function index, LVEF left ventricle ejection fraction, CI cardiac index, SVI stroke volume index, HR heart rate, SAP systolic arterial pressure, MAP mean arterial pressure, PP pulse pressure, CVP central venous pressure, GEDVi global end-diastolic volume index, Ea effective arterial elastance, TAC total arterial compliance, SVRi systemic vascular resistance index
  3. Significant results (p < 0.05) are highlighted in italics
  4. aCalculated with Student’s T test unless indicated
  5. bCalculated with Wilcoxon’s rank test
