Supplementary Fig. 2 — The diagnostic efficiency of susceptibility of left cerebral cortical vein for the discrimination between mTBI patients, non-AI patients, AI patients and HCs using ROC.

The best cut-off susceptibility of left cerebral cortical vein for the discrimination between mTBI patients and HCs was 159 ppb with a sensitivity of 73% (95% CI: 58–85), specificity 50% (95% CI: 32–68), and AUC value 0.62 (95% CI: 0.51–0.73) (panel a). The best cut-off susceptibility of left cerebral cortical vein for the discrimination between non-AI patients and HCs was 159 ppb with the sensitivity 84% (95% CI: 67–95), specificity 50% (95% CI: 32–68), and AUC value 0.67 (95% CI: 0.54–0.79) (panel b). The best cut-off susceptibility of left cerebral cortical vein for the discrimination between AI patients and HCs was 153 ppb with sensitivity 94% (95% CI: 70–100), specificity 22% (95% CI: 9–40), and AUC of 0.52 (95% CI: 0.37–0.66) (panel c).
