Table 3 Results of multivariable analysis using the Cox proportional hazards model for Condition A (qualified success)

From: Efficacy and safety of Ex-PRESS® mini shunt surgery versus trabeculectomy for neovascular glaucoma: a retrospective comparative study

Variable RR 95% CI P valuea
Ex-PRESS procedure (vs trab) 3.96 0.15 to 1.26 0.012
Preoperative IOP (per mm Hg) 1.06 0.00014 to 0.12 0.0495
Age (per year) 0.969 −0.078 to 0.015 0.185
Avitreous status 1.38 −0.96 to 1.68 0.629
