Box plot of plasma α-synuclein levels in Controls, iPD patients and <i>LRRK2</i> PD patients.

<p><b>A)</b> Total α-synuclein (ng/ml). <b>B)</b> α-Synuclein oligomers in Counts Per Second (CPS). <b>C)</b> % Ratio Oligomers to total α-synuclein. Boxes show the minimum, maximum and median level for each group, together with the lower and upper quartile. Symbols (unfilled circles) outside the range represent outliers.</p

ROC curve for α-synuclein levels in iPD patients.

<p>A receiver operating characteristic (ROC) curve was generated for total α-synuclein in iPD patients. The dashed reference line represents the ROC curve for a test with no discriminatory ability. The area under the ROC curve (AUC) is displayed on the graph with the 95% confidence interval shown between the parentheses (0.524–0.667). The level of significance was set at <i>p</i><0.05. No possible cutoff value was derived from the analysis.</p
