IL-1β level in plasma of aMCI and AD patients, as well as controls, and its correlation with clinical characteristics. a Concentration of IL-1β protein as measured by ELISA in plasma from patients with aMCI or AD, and controls. b–d Correlation of the IL-1β level in plasma and the Aβ1-42 level in CSF from patients with aMCI, and MoCA and MMSE scores. e–g Correlation of the IL-1β level in plasma and the Aβ1-42 level in CSF from patients with AD, and MoCA and MMSE scores. **P < 0.01, ****P < 0.001. n = 20 for control, n = 33 for aMCI, n = 33 for AD. Data are expressed as means ± SEM. One-way ANOVA for a. The correlation was determined by calculating correlation coefficients
