Fig. 4 — The diagnostic efficiency of susceptibility of straight sinus for the discrimination between mTBI patients, non-AI patients, AI patients and HCs using the receiver operating characteristic curve (ROC).

Panel a. The best cut-off susceptibility of straight sinus for the discrimination between mTBI patients and HCs was 298 ppb with the sensitivity (88%, 95% CI: 75–95), specificity (69%, 95% CI: 50–84), and AUC value (0.84, 95% CI: 0.74–0.91). Panel b. The best cut-off value for the discrimination between non-AI patients and HCs was 273 ppb with the sensitivity (75%, 95% CI: 57–89), specificity (84%, 95% CI: 67–95), and AUC value (0.86, 95% CI: 0.75–0.93). Panel c. The best cut-off value for the discrimination between AI patients and HCs was 290 ppb with the sensitivity (81%, 95% CI: 54–96), specificity (69%, 95% CI: 50–84), and AUC value (0.80, 95% CI: 0.66–0.90).
