Associations between global cortical non-displaceable binding potential of Aβ and vessel densities/foveal avascular zone, given in ratios due to a log transformation applied to the dependent variable

	Global cortical non-displaceable binding potential of Aβ
	Ratio	Raw p value	95% CI	Adjusted p value
Retinal vessel density
Inner ring macula*	2.28	0.016	1.21 to 6.41	0.064
Outer ring macula*	3.74	0.052	0.99 to 14.1	0.156
Around optic nerve head*	0.86	0.654	0.43 to 1.69	0.654
Foveal avascular zone (mm2)	0.59	0.356	0.19 to 1.80	0.712

GEE, corrected for age, gender, scan quality and diagnosis of diabetes.

*Reported in steps of 10. Adjusted p values were calculated using the Holm-Bonferroni method.

Aβ, amyloid-beta; GEE, generalised estimating equations.
