Connectivity of the insular subdivisions differentiates posttraumatic headache-associated from nonheadache-associated mild traumatic brain injury: an arterial spin labelling study

Table 3 Results of ROC for the discrimination between mTBI + PTH and mTBI-PTH patients

Functional connectivity index	AUC (95%CI)
Right vAI – left MCC	0.732(0.631–0.818)
Left PI – left SMA	0.809(0.715–0.883)
Left PI – right thalamus	0.733(0.632–0.819)
Left dAI – left MCC	0.735(0.634–0.820)
Left dAI – right ROL	0.731(0.630–0.818)
Combination of five indexes	0.882(0.799–0.939)

AUC, the area under the ROC curve; CI, confidence intervals; R_vAI, right ventral anterior insula; L_PI, left posterior insula; L_dAI, left dorsal anterior insula; MCC, middle cingulate gyrus; SMA, supplementary motor area; ROL, Rolandic operculum
