Figure 3From: A randomised controlled trial of an open lung strategy with staircase recruitment, titrated PEEP and targeted low airway pressures in patients with acute respiratory distress syndromeStatic lung compliance measured in ventilated patients for seven days (mean ± SE). There was a significant overall improvement in static lung compliance in the PHARLAP group compared to control group patients. A = missing data analysed as random P = 0.001, B = last observation carried forward P = 0.01.Back to article page
