Kernel reads outperformed many clinical benchmarks for cognitive impairment screening, including:

1) Mini-Cog (3-min memory test): Sensitivity 76-91%, specificity 73-86%.

2) Newly approved Lumipulse plasma pTAU217 test: XX% accuracy, AUC XXXX for distinguishing brain Tau levels.

3) In just XX minutes, Kernel's light-based measurement clearly enhanced and surpassed quick surveys and simple cognition tests for early dementia detection, approaching the accuracy of FDA-approved blood tests.
