Results from Multiple Regression Analysis of all Scans Combined

	β	SE β	P value
Difference in signal strength	1.55	0.33	< .0001
Difference in nasal minus temporal RNFL thickness	0.08	0.02	< .0001
Difference in superior minus inferior RNFL thickness	0.00	0.02	.62
Visit (same vs separate)	−0.2	0.3	.53

β = unstandardized β coefficient; RNFL = retinal nerve fiber layer; SE β = standard error β.
