Table 3 Multivariate logistic regression model for the length of ICU stay

From: ICU management based on PiCCO parameters reduces duration of mechanical ventilation and ICU length of stay in patients with severe thoracic trauma and acute respiratory distress syndrome

Length of ICU stay (bivariate: >7 days or ≤7 days) Odds ratio Lower limit of 95% CI Upper limit of 95% CI P

Gender (male as the reference) 1.16 0.59 1.74 0.863
Age (with 1 year increase) 1.11 0.98 1.21 0.536
