From: Impact of cerebral blood flow and amyloid load on SUVR bias

GCA	SUVR		SUVR_bias (%)
GCA	Coefficient estimate	95% Confidence interval	Coefficient estimate (%)	95% Confidence interval (%)
DVR	1.31^‡	1.19 to 1.44	9.46	− 0.78 to 19.69
R₁	− 0.17	− 0.49 to 0.14	− 13.43	− 39.00 to 12.14
Age	0.00	0.00 to 0.00	0.10	− 0.16 to 0.37
Sex	0.00	− 0.05 to 0.05	− 0.12	− 4.19 to 3.95
APOE-ε4	0.02	− 0.03 to 0.07	2.00	− 1.96 to 5.97

Females and APOE-ε4 non-carriers were used as reference groups
GCA: global cortical average, *p < 0.05, **p < 0.01, ^‡p < 0.001
