Figure 4. Acceleration point estimates and 95% confidence intervals.

Estimates of the initial acceleration points and 95% confidence intervals for all outcomes are plotted against baseline CSF Aβ₄₂. β-Amyloid pathology increases from left to right. The dashed black line is the conventional threshold for amyloid positivity (192 ng/L). ADAS = Alzheimer's Disease Assessment Scale; BNT = Boston Naming Test; CDR-SB = Clinical Dementia Rating Sum of Boxes; dRAVLT = delayed Rey Auditory Verbal Learning Test; FAQ = Functional Assessment Questionnaire; FDG = ¹⁸F-fluorodeoxyglucose; MMSE = Mini-Mental State Examination.
