Plasma levels of IL-1β in PD patients and healthy controls, and the correlation with clinical characteristics. a Measurement of IL-1β concentration by MSD immunoassay in plasma from PD (solid diamond) and healthy control (solid circles) subjects. n = 24 for control, n = 43 for PD groups respectively. Data are expressed as mean ± SEM, one-way ANOVA. b Correlation of IL-1β levels in plasma from PD patients with H-Y stage. c Correlation of IL-1β levels in plasma from PD patients with UPDRS part I scores. d Correlation of IL-1β levels in plasma from PD patients with UPDRS part III scores. The correlation was established by calculating correlation coefficients
