What amyloid threshold level is required for optimal clinical benefit in early AD?

PARTIALLY ADDRESSED

While the study demonstrates dose-response relationships between amyloid levels and outcomes, it doesn't establish specific threshold values for clinical benefit. Defining these thresholds is critical for treatment optimization and stopping rules in clinical practice.
