The effect of ventilation strategy in the first 24 h on the PARDS severity distribution, mortality and VFD. On the left the group of subjects receiving CMV the first 24 h after onset, on the right the group who are switched from CMV to HFOV within the first 24 h after onset. Grey bars represent number of cases with mild, moderate and severe PARDS. Orange dots depict median (with interquartile range) VFD-28 (bottom Y-axis) and blue triangles represent mortality (%) (upper Y-axis)
