Multivariate Regression Analysis Comparing Brightness Levels Between Quadrants in Pachychoroid Eyes

					95% Confidence Interval
Quadrant	Coefficient	Standard Error	t-Statistic	P Value	Lower	Upper
Superonasal	Reference
Superotemporal	1.04	1.51	0.69	0.493	–1.95	4.02
Inferonasal	9.35	1.51	6.19	<0.001	6.35	12.34
Inferotemporal	17.23	1.98	8.72	<0.001	13.31	21.16

Multivariate linear regression analysis was performed comparing average brightness level between quadrants in pachychoroid eyes, controlling for patient-eye-specific fixed effects (i.e., including indicator variables for the interaction between patient and eye). More positive values correspond to brighter quadrants. Bold values denote significance set at P < 0.05.
