Patients with FO+ had significantly higher cumulative fluid balance during their ICU stay compared to those without FO (8.8 \u00b1 7.0 vs. 5.5 \u00b1 5.4 litres; P = 0.009), VE (9.9 \u00b1 6.5 vs. 1.5 \u00b1 1.5 litres; P &lt; 0.001), total body water (63.0 \u00b1 9.5 vs. 52.8 \u00b1 8.1%; \nP &lt; 0.001), and extracellular water (27.0 \u00b1 7.3 vs. 19.6 \u00b1 3.7 litres; P &lt; 0.001). The presence of 5%, 7.5%, and 10% fluid overload was directly associated with increased ICU mortality rates.

FO is an independent prognostic factor because neither APACHE-II, SOFA, nor SAPS-II significantly differed on admission between survivors and non-survivors.
