Table 3 Predictive value of ADC for diagnosis of malignancy by receiver operating characteristic curve (ROC)

From: Diffusion-weighted magnetic resonance imaging in differentiation between different vertebral lesions using ADC mapping as a quantitative assessment tool

Diagnosis	ADC
Diagnosis	AUC	Cutoff	Sens%	Spec%	PPV	NPV	P value
Malignant	0.807	≤ 0.9 × 10³	85.7	91.3	75.0	95.5	0.0108*
Benign	0.807	> 0.9 × 10³	91.3	85.7	95.5	75.0	0.0108*

AUC area under curve, Sens sensitivity, Spec specificity, PPV positive predictive value, NPV negative predictive value
*P ≤ 0.05 is considered significant
