- Baseline IOP	1.05 (1.04 – 1.06)	P<0.001	1.10 (1.08 – 1.11)	P<0.001

Note:

Reference for Multivariate Model: age, gender ((a) reference: female), race ((b) reference: Non-Hispanic White), glaucoma type ((c) reference: Primary open angle glaucoma), severity ((d) reference: mild glaucoma)), and baseline IOP

^(e)Other race = non-Hispanic/Latino Asian, or other

^(f)Secondary glaucoma = glaucoma secondary to medications, trauma, inflammation, unspecified
