p-tau231 reflects earlier amyloid-driven changes in entorhinal cortex while p-tau217 reflects downstream neuronal involvement. The combination captures the full spectrum of amyloid-to-tau propagation resolution. However, the composite algorithm is not operationally defined, weighting schemes are unspecified, and temporal window evidence from natural disease course may not transfer to treatment kinetics. Addition of p-tau231 may increase assay complexity without proportional predictive gain.

Dimension Scores
How to read this chart:
Each hypothesis is scored across 10 dimensions that determine scientific merit and therapeutic potential.
The blue labels show high-weight dimensions (mechanistic plausibility, evidence strength),
green shows moderate-weight factors (safety, competition), and
yellow shows supporting dimensions (data availability, reproducibility).
Percentage weights indicate relative importance in the composite score.
