Longitudinal measures of (a) extravascular lung water (EVLW) and (b) oxygenation (arterial oxygen tension [PaO₂]/inspired fractional oxygen [FiO₂] ratio) in patients with severe sepsis, stratified by survival. Vertical bars indicate standard errors. *Significant between-group differences at the marked time points; P < 0.001 for EVLW differences over time, by analysis of variance.
