Diagnostic values of combined long-chain acylcarnitines. (A,B) Receiver operating characteristics (ROC) curves (solid) for plasma LCACs and corresponding AUC statistics for the true positive rate for Parkinson’s disease diagnosis in the 1st cohort. A is for Parkinson’s disease, and B for H&Y stage I Parkinson’s disease. (C,D) ROC curves (solid) for plasma LCACs and corresponding AUC statistics for the true positive rate for Parkinson’s disease diagnosis in the 2nd cohort. C is for Parkinson’s disease and D for H&Y stage I Parkinson’s disease. Abbreviations: Parkinson’s disease = PD; H&Y = Hoehn and Yahr stage; AUC = area under the curve.
