  • Note:—Correlation coefficients derived from mixed effects regression analysis, accounting for correlations between optic nerves in the same individuals. Statistical significance is as follows: * P < .01), ‡ P < .001, and § P < .0001). Prior ON status is denoted as follows: ±, all optic nerves (197 nerves, 104 individuals); −, no prior ON (158 nerves, 96 individuals); and +, prior ON (35 nerves, 32 individuals).
