TABLE 1.

Summary of slopes versus eccentricity and their p-values for both fixed (fixed intercept and slope for each subject) and mixed (fixed intercept and slope, with independent random intercept and slope for subject grouping) effects models.

Model Type	Slopes vs. eccentricity	Extrema (normalized intensity)					Stratum thickness (% IPL thickness)					Transition (% IPL thickness)
		S5	S4	S3	S2	S1	S5	S4	S3	S2	S1	S4–S5	S3–S4	S2–S3	S1–S2
Fixed effects	vs. eccentricity (mm)	N/A	0.0040	−0.016	−0.022	−0.037	0.57	−0.30	0.33	0.95	−1.2	2.2	−1.9	2.0	−0.92

Mixed effects	vs. eccentricity (mm)	N/A	0.0041	−0.015	−0.021	−0.036	0.60	−0.51	0.61	0.62	−1.08	1.8	−1.5	1.8	−0.85

Note that the S5 peak was analyzed separately in Figure 8 with quadratic models and is not included here. A positive slope indicates an increase in the parameter with eccentricity. Both models indicate that the S1–S3 extrema decrease with eccentricity, that the thickness of S1 decreases with eccentricity, and that the S4–S5 and S2–S3 transition widths increase with eccentricity, while the S1–S2 and S3–S4 transition widths decrease with eccentricity. The slope unit is the column unit divided by the row unit (mm).
