Associations between B2M and CSF AD biomarkers. Multiple linear regression models were used to examine the associations between the plasma B2M with cerebrospinal fluid (CSF) Aβ_1–42 (A), T-tau (B), P-tau (C), Aβ_1–42/Aβ_1–40 (D) T-tau/Aβ_1–42 (E), and P-tau/Aβ_1–42 (F), adjusting for age, sex, education level, APOE ɛ4 carrier statuses, and MMSE. Abbreviations: B2M, β₂-microglobulin; APOE, apolipoprotein E
