Fig. 2From: Utility of plasma Neurofilament light as a diagnostic and prognostic biomarker of the postural instability gait disorder motor subtype in early Parkinson’s diseaseBaseline plasma NfL discriminates PD from healthy controls. a Receiver operating characteristic curve analysis in PD vs HC b Contour plot showing predicted probability of clinical diagnosis of PD at different NfL levels and age group. The darker shade of red indicates higher risk and darker blue indicates lower risk of PD. The solid line depicts the risk of PD using multivariable logistic regression model adjusted NfL x age interaction term.
