Estimates of the corneal index odds ratio and standard error (SE) for progressive visual field loss in patients with well-controlled intraocular pressure after adjustment for potential confounder factors.

Variable	Multivariable Model 3
Variable	Odds Ratio (SE)	P Value^*
Corneal index (per SD lower)	1.68 (0.38)	0.021
Baseline MD (dB)	0.99 (0.03)	0.789
Age (years)	1.01 (0.02)	0.614
Race (African American)	0.70 (0.31)	0.430
Mean IOP (mmHg)	0.96 (0.09)	0.642
Previous cataract surgery	2.42 (1.14)	0.061
QIC	188.260

Generalized estimating equations

SD = standard deviation; SE = standard error; MD = mean deviation; IOP = intraocular pressure; QIC = quasi-likelihood under the independence model criterion.
