Table 2. Structural connectivity changes.
Data shows the changes in structural connectivity between white matter seeds and medial or lateral frontal cortex, over one year (visit 1 to visit 4), in persisting and recovering back pain (SBPp and SBPr). Values are normalized probability of structural connectivity between white matter seeds and medial and lateral prefrontal cortices. Ecap, r-Icap, slf are white matter seeds, shown in figure 3A.

mfc = the grey-white matter edge of the whole medial prefrontal cortex; lfc = the grey-white matter edge of the whole lateral prefrontal cortex, see figure 1.
Values are Mean ±SEM. (ns = not significant; ** p < 0.01)
