Fig. 2

Specific volume change distribution vs. survival status at 90 days. sΔVx: distribution of specific volume change centre-of-mass on the lateral (x) axis. Inset figure shows the direction of change; sΔVz: distribution of specific volume change on the apical-caudal (z) axis. Values vary on a relative scale from − 1 (-100%) to + 1 (+ 100%) with reference to the origin (0) of a normalized grid on which the individual datasets are projected. Red line indicates median value. Note the more caudal and less left-skewed sΔV centre-of-mass in survivors vs. non-survivors
