Visualization of SVM results by using FC values between the left NAc and the bilateral medial prefrontal cortex to differentiate patients with OCD from HCs. Left: 3D visualization of SVM with the best parameters; right: classification map of the FC values of the bilateral middle cingulate cortex; SVM: support vector machine; FC: functional connectivity; NAc: nucleus accumbens; OCD: obsessive-compulsive disorder; HCs: healthy controls.
