Odds ratio estimates for decrease in pore size (mean pore area to disc area ratio) in a univariable model

	Odds ratio	95% CI	p Value
Patient specific factors
Age	1.02	(0.94 to 1.12)	0.59
Female sex	0.48	(0.14 to 1.74)	0.27
Diagnosis of normal pressure glaucoma	0.73	(0.20 to 2.57)	0.62
Eye specific factors
Mean intraocular pressure	1.00	(0.98 to 1.02)	0.86
Vertical cup to disc ratio*	2.78	(1.28 to 6.00)	0.01
Neural rim area to disc area ratio*	0.34	(0.15 to 0.74)	0.01
Total pore area to disc area ratio†	0.64	(0.20 to 1.99)	0.44

*Odds ratio is given for an increase of 0.10 of factor (otherwise for a 1 unit increase).

†Odds ratio is given for an increase of 0.01 of factor.
