To statistically evaluate the potential of sCD163 and the other assayed markers to predict PD diagnosis (PD versus HC) and PD phenotypic scores (UPDRS‐III, MoCA, MMSE O, and MMSE O + C), we used receiver‐operating characteristic (ROC) analysis [area under the curve (AUC) estimates] and linear regression (regression slopes) (Supporting Information Figs. S3, S5, and S6). The gene discussed is CD163; the disease is Parkinson disease.
