Fig. 3From: Is intrinsic lumbar spine shape associated with lumbar disc degeneration? An exploratory studyLDD correlates with intrinsic shape (Mode 7 (M7)). The figure (left) represents a negative correlation between M7 scores (SD) and LDD (rp = −0.56, p ≤ 0.001). The figure (right) is a graphical representation of this; the greater degree of LDD the smaller the intervertebral spaces (L4-S1) (from blue (+ 2SD) to red (− 2SD)).
