Kaplan-Meier survival curves, excluding the eyes that underwent combined TRAB and GDIS, evaluated by Criterion 1: 5 < IOP ≤ 21 mmHg. GDIS, glaucoma device implant surgery; IOP, intraocular pressure; TRAB, trabeculectomy. Log-rank test: P = 0.2, Cox proportional hazard model: HR: 0.81, 95% CI: 0.46–1.44, P = 0.48. Shaded regions indicate the 95% confidence intervals (the first GDI group: thin shaded region, the second GDI group: thick shaded region). horizontal axis: months
