Kaplan-Meier survival probability by lung image-derived variable, comparing: Q1-Q2: 1st and 2nd quartiles; and Q3- Q4; 3rd and 4th quartiles. A: Vrec: Global recruited lung tissue volume between 5 and 15 cmH2O; sΔVx: Lung volume change spatial distribution along the left – right axis; sΔVz: Lung volume change spatial distribution along the basal – apical axis. D: the sΔV x, y and z axis direction of change and orientation in the supine position
