Serum Butyrylcholinesterase Activity: A Biomarker for Parkinson’s Disease and Related Dementia

Figure 2

(a) ROC curve of serum BChE activities for detecting PD patients. (b) A linear correlation is observed between BChE activities and UPDRS scores. (c) A linear correlation is observed between BChE activities and MMSE scores. (d) ROC curve of serum BChE activities for detecting PD patients with dementia. ROC, receiver operating characteristic; BChE, butyrylcholinesterase; PD, Parkinson’s disease; AUC, area under the curve; CI, confidence interval; UPDRS, Unified Parkinson’s Disease Rating Scale; MMSE, Mini-Mental State Examination.
