Receiver operating characteristic (ROC) curves of the four models after backward logistic regression. Model B showed improved accuracy (difference between areas, 0.05; P = 0.03) and sensitivity compared to the combination of PLR and serum NSE levels. A Area under the ROC curve (AUC) 0.86 (95% confidence interval [CI] 0.79–0.92); 30% sensitivity for 100% specificity. B AUC 0.91 (95% CI 0.86–0.96); 51% sensitivity and 100% specificity. C AUC 0.90 (95% CI 0.85–0.95); 54% sensitivity for 100% specificity. D AUC 0.90 (95% CI 0.85–0.95); 53% sensitivity and 100% specificity. PLR, pupillary light reflex; NSE, neuron-specific enolase; ADC, apparent diffusion coefficient; mean whole brain ADC = the average ADC value of the entire brain volume; ADC-PercentValue 600 = the percentage of voxel with ADC values below 600 × 10−6mm2/s among the entire brain volume; ADC-PercentValue 650 = the percentage of voxel with ADC values below 650 × 10−6mm2/s among the entire brain volume
