Comparison of extravascular lung water indexed to predicted body weight. Comparison of extravascular lung water indexed to predicted body weight of patients with acute lung injury (ALI)/acute respiratory distress syndrome (ARDS), cardiogenic edema, and pleural effusion with atelectasis on the day of enrollment and the maximal value during the study period. (A) Extravascular lung water indexed to predicted body weight (EVLWI) on the day of enrollment was significantly higher in ALI/ARDS patients than in pleural effusion with atelectasis patients and cardiogenic edema patients. EVLWI was also higher in cardiogenic edema patients than in pleural effusion with atelectasis patients. (B) Differences were found when the maximal EVLWI value was compared between day 0 and day 2. Data presented as median (interquartile range). *P < 0.01 vs. pleural effusion with atelectasis. **P < 0.01 vs. cardiogenic edema. EVLWI-0, extravascular lung water index on day of enrollment; maxEVLWI, maximal value of extravascular lung water index from days 0 to 2.
