Figure 3. — Correlations of changes in theta band global efficiency with changes in clinical measures. Bivariate correlations of changes in the graph theory-based measure global efficiency (gEff) in the theta band with changes in average pain intensity, pain-related disability (Pain Disability Index [PDI]), and depression (Beck Depression Inventory II [BDI]) are depicted. Δ = change = follow-up values—baseline values.
