a
Applicable to discrete variables only.
b
Correlation coefficient used for continuous variables and odds ratio used for discrete variables. Odds ratios for PAPi reflect associations with decreasing PAPi.
CVP, central venous pressure; CI, confidence interval; ICU, intensive care unit; Min, minimum; Max, maximum; PAPi, pulmonary artery pulsatility index; RRT, renal replacement therapy.
