Table 2.

Comparison of GVD scores from the two protocols

	CERAD protocol GVD score
Tau-IR GVD scorea	No	Yes
No	3 (5)	1 (1)
Mild	21 (37)	18 (26)
Moderate	21 (37)	31 (45)
Severe	12 (21)	19 (28)

Data presented as n (%). Some GVD scores were marked as missing from the CERAD assessment, and therefore data are for cases which did have CERAD GVD scores (n = 126)
