Linear Regression Models to Predict Mean Deviation Associated with Blood Flow, Rim Area, and Retinal Nerve Fiber Layer Thickness in Glaucoma Patients

Model	Variable 1			Variable 2			Total R2
	Parameter (dB)*	Slope (Pvalue)	R2	Parameter (dB)*	Slope (Pvalue)	R2
1	Blood flow	1.91 (<0.001)	0.29
2	cSLO rim area	1.11 (0.03)	0.10
3	FDOCT RNFL thickness	3.29 (0.01)	0.13
4	Blood flow	1.93 (<0.001)	0.26	cSLO rim area	1.15 (0.006)	0.10	0.36
5	Blood flow	1.62 (0.001)	0.24	FDOCT RNFL thickness	2.56 (0.03)	0.09	0.33

FDOCT, Fourier-domain optical coherence tomography; RNFL, retinal nerve fiber layer; cSLO, confocal scanning laser ophthalmoscopy.
