Table 5 Analysis of the diagnostic ability of ADC and FA to differentiate between patients and control groups

From: Magnetic resonance diffusion tensor imaging of acute spinal cord injury in spinal trauma

ROC curve between patient and control
  Cutoff Sens. Spec. PPV NPV AUC 95% CI p value
FA value at site of injury ≤ 0.403 93.33% 100.0% 100.0% 83.3% 0.957 84–99.6% < 0.001*
ADC value at site of injury ≤ 1.31 66.67% 80.00% 90.9% 44.4% 0.712 54.7–84.4 0.051*
  1. Sens. sensitivity, spec. specificity, PPV positive predictive value, NPV negative predictive value, AUC area under the curve, CI confidence intervals
  2. p value: probability for independent samples t test for association between patients and control group
  3. *Significant p value (< 0.05)
