From: Assessment of BDNF serum levels as a diagnostic marker in children with autism spectrum disorder
The area under the ROC curve is associated with the discriminating power of a diagnostic test. The values of the ROC curve show the difficulty in discriminating the two groups from the BDNF. The ROC curve for the possible diagnosis of ASD based on serum the BDNF levels and probabilities estimated by multiple logistic regression. In the present configuration the area under the curve (AUC) were 0.758 (95% CI 0.658–0.858) for BDNF and 0.869 (95% CI 0.795–0.944) according to multiple logistic regression.
