Multiple logistic regression analysis with hospital mortality as the dependent outcome variable
| Odds ratio (95% CI) | p value | |
| Without FB | ||
| Age (per year) | 1.04 (1.02, 1.06) | <0.0001 |
| SAPS II (per point) | 1.05 (1.03, 1.06) | <0.0001 |
| RRT | 2.41 (1.23, 4.73) | 0.010 |
| Dx: Renal | 0.08 (0.01, 0.58) | 0.012 |
| R: Fluid overload | 0.44 (0.23, 0.88) | 0.019 |
| Dx: Respiratory | 1.93 (1.06, 3.53) | 0.033 |
| PiCCO | 1.58 (0.92, 2.71) | 0.10 |
| With FB | ||
| Age (per year) | 1.04 (1.02, 1.06) | <0.0001 |
| SAPS II (per point) | 1.04 (1.02, 1.06) | <0.0001 |
| RRT | 2.53 (1.24, 5.16) | 0.011 |
| Dx: Renal | 0.47 (0.22, 0.98) | 0.044 |
| R: Fluid overload | 0.08 (0.01, 0.7) | 0.022 |
| Mean daily FB (ml/day) | 1.0002 (1.0001, 1.0004) | 0.0073 |
| PiCCO | 1.38 (0.78, 2.44) | 0.27 |
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.
