Fig. 5. Lung injury score of the three groups. Boxes = 25th and 75th percentiles, and the median value; whiskers = minimum and maximum values. PC = pressure-regulated volume control mode with inspiratory time at 20% of total cycle time; VC 20= volume-control mode with inspiratory time at 20% of total cycle time; and VC 50= volume-control mode with inspiratory time at 50% of total cycle time.
