Difference in vessel densities and foveal avascular zone area between amyloid-positive and amyloid-negative participants

	Aβ+ versus Aβ–
	Difference	Raw p value	95% CI	Adjusted p value
Retinal vessel density
Inner ring macula	0.81	<0.001	0.36 to 1.26	0.002
Outer ring macula	0.50	0.012	0.11 to 0.90	0.024
Around optic nerve head	0.83	0.005	0.25 to 1.42	0.015
Foveal avascular zone (mm2)	−0.02	0.387	−0.05 to 0.02	0.387

Adjusted p values were calculated using the Holm-Bonferroni method.

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

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