Quantification of the percent of total vessel surface area that was Congo red-positive in various regions of three mice with the highest CAA grade

Vascular amyloid	Pia	Cortex	Hippocampus	Thalamus
Percent of Congo red-positive surface area	61  ±  1.3%	8  ±  1.8%	8  ±  2.6%	13  ±  2.2%

The mean plaque load of these three mice was 20%. Values are shown ± SEM.
