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

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

Variable	RR	95% CI	P value^a
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
