Results of the Multiple Regression of Fixation Stability (BCEA) on Microsaccade Amplitude, Slow Drift Amplitude, and Observer Group (With Macular Disease or Not)

	Estimate	SE	t Value	Pr(>|t|)
Intercept	−3.046	0.292	−10.434	<0.00001
Microsaccade amplitude	1.290	0.201	6.409	<0.00001
Slow drift amplitude	0.465	0.221	2.102	0.0454
Observer grouping	0.415	0.155	2.673	0.0128

Residuals SE: 0.256 on 26 df. Multiple R² = 0.901; adjusted R² = 0.889 (P < 3.67e⁻¹³).
