Table 2.

The age slopes and $p$ values with (1) “univariate regression” from age to global and quadrant-specific cpRNFLTs in comparison to the slopes and $p$ values of age and scan diameter with (2) “multivariate regression” from age and diameter to global and quadrant-specific cpRNFLTs. The table is to demonstrate how the ocular magnification can bias the estimation of age-related thinning rate of global and quadrant cpRNFLT as most previous works have not included ocular magnification in their cpRNFLT norm model.

RNFLT	Univariate		Multivariate
	Age slope ($\mu \mathrm{m}/\text{year}$)	$p$ value for age	Age slope ($\mu \mathrm{m}/\text{year}$)	$p$ value for age	Diameter slope ($\mu \mathrm{m}/\mathrm{mm}$)	$p$ value for diameter
