Duration of glaucoma therapy (within 1 year vs. after 1 year before trab)	0.95	0.35 to 2.64	0.928

CI, confidence interval; IOP, intraocular pressure; RR, relative risk; trab, trabeculectomy; vs., versus.

^a P values were determined by means of the Wald test in the Cox proportional hazards model.

Significant at P < 0.05.
