Fig. 3From: Fibroblast growth factor 21 associating with serotonin and dopamine in the cerebrospinal fluid predicts impulsivity in healthy subjectsReceiver operating characteristic (ROC) curve analysis showed that the level of CSF FGF21 may be used to predict high impulsivity risk. The area under the ROC curve is 0.79 with a sensitivity of 70.27% and specificity of 83.15% (P < 0.001)Back to article page
