  1. Odds ratios are presented as medians (with 25th and 75th percentiles). R2 = 0.205 without FB and 0.191 with FB. CI, confidence interval; Dx, diagnostic group; FB, fluid balance; PiCCO, pulse contour cardiac output; R, reason for catheter insertion; RRT, renal replacement therapy; SAPS II, simplified acute physiology score.
