| ROI | Parameter | AUC | 95% CI |
|---|---|---|---|
| SCC | FA | 0.920 | 0.823–0.934 |
| LN | FA | 0.571 | 0.530–0.612 |
| MD | 0.742 | 0.702–0.784 | |
| FWM | FA | 0.581 | 0.551–0.611 |
| MD | 0.762 | 0.744–0.791 | |
| PLIC | FA | 0.938 | 0.840–0.950 |
| MD | 0.807 | 0.722–0.838 | |
| CP | FA | 0.601 | 0.591–0.611 |
The AUCs of FA in the SCC, LN, FWM, PLIC, and CP were 0.920, 0.571, 0.581, 0.938, and 0.601. The AUCs of MD in the LN, FWM, and PLIC were 0.742, 0.762, and 0.807. DTI, diffusion tensor imaging; ROIs, regions of interest; AUC, area under the curve; CI, confidence interval; SCC, splenium of the corpus callosum; FA, fractional anisotropy; LN, lentiform nucleus; MD, mean diffusivity; FWM, frontal white matter; PLIC, posterior limbs of the internal capsule; CP, cerebral peduncle.
