Multiple linear regression analysis with mean daily fluid balance (ml/day) as the dependent outcome variable
| Coefficient (95% CI) | p value | |
| R: Other types of shock | 1,027 (522, 1,532) | <0.0001 |
| R: Fluid overload | -770 (-1,210, -331) | 0.0006 |
| SAPS II (per point) | 15.5 (5.8, 25.1) | 0.0018 |
| Inotropes | -536 (-954, -119) | 0.012 |
| Heart rate (beats per minute) | 9.8 (2.2, 17.5) | 0.012 |
| Dx: Others | 713 (76, 1,351) | 0.028 |
| COPD | 475 (27, 923) | 0.038 |
| CVP | -31.9 (-62.1, -1.6) | 0.039 |
| Creatinine (μmol/l) | -1.3 (-2.6, -0.0) | 0.044 |
| PiCCO | 209 (-147, 564) | 0.25 |
Coefficient values are presented as medians (with 25th and 75th percentiles). R2 = 0.237. CI, confidence interval; COPD, chronic obstructive pulmonary disease; CVP, central venous pressure; Dx, diagnostic group; PiCCO, pulse contour cardiac output; R, reason for catheter insertion; SAPS II, simplified acute physiology score.
