β‐coefficients and their 95% confidence intervals showing difference in endothelial cell density (ECD) loss between the quadrant closest to the Baerveldt (BV) and the other quadrants

Parameter	Estimate	Sig.	95% Confidence interval
			Lower bound	Upper bound
Intercept	1939	<0.001	1776	2101
β 1, the effect of time after a follow‐up of t months	−10.6	<0.001	−12.6	−8.7
β 2, other quadrants	14.3	0.408	−19.6	48.2
β 2, PQC	0
β 3, the interaction effect time – other quadrants	3.23	0.003	1.10	5.36
β 3,the interaction effect time – PQC	0

PQC = peripheral quadrant closest to the BV GDD tube.
