The diagnostic efficiency of susceptibility of right septal vein for the discrimination between mTBI patients, non-AI patients, AI patients and HCs using ROC.
The best cut-off susceptibility of right septal vein for the discrimination between mTBI patients and HCs was 153 ppb with a sensitivity of 73% (95% CI: 58–85), specificity 41% (95% CI: 24–59), and AUC value 0.53 (95% CI: 0.42–0.65) (panel a). The best cut-off susceptibility of right septal vein for the discrimination between non-AI patients and HCs was 153 ppb with the sensitivity 72% (95% CI: 53–86), specificity 41% (95% CI: 24–59), and AUC value 0.50 (95% CI: 0.38–0.63) (panel b). The best cut-off susceptibility of right septal vein for the discrimination between AI patients and HCs was 146 ppb with sensitivity 63% (95% CI: 35–85), specificity 69% (95% CI: 50–84), and AUC of 0.59 (95% CI: 0.44–0.73) (panel c).
