Schlemm's canal (SC) cross-sectional area (CSA) as measured (1) comprehensively in 31 B-scans within a 1 mm segment of SC, (2) in a single subjective location, and three in five random frames is presented as mean±SD

	Comprehensive 31 B-scans	Subjectively identified frame	Random 5 frame
CSA (μm2)	4064±1308	7614±2162	4175±1045
GEE significance level		<0.0001	0.6537
SEM goodness of fit		0.669	0.713

Significance levels of a general estimating equation comparison with the gold standard comprehensive measurements, and goodness of fit of the structural equation models are presented.

GEE, general estimating equation; SEM, structural equation modelling.
