Fig. 2From: Integrated robotics platform with haptic control differentiates subjects with Parkinson’s disease from controls and quantifies the motor effects of levodopaDifferentiating Controls and PD subjects using ROC Analysis. ROC analyses conducted on robotic parameters for the a object hit task, b object hit and avoid task, c passive stretch task and d unloading task between controls and subjects with PD. The AUC for each parameter is denoted in the brackets). ROC = Receiver operating characteristic. AUC = area under the curveBack to article page
