Bold indicates statistical significance.
CE = cataract extraction; CI = confidence interval, given for significant variables; GATT = gonioscopy-assisted transluminal trabeculotomy; HR = hazard ratio, given for significant variables; IOP = intraocular pressure; MD = mean deviation; POAG = primary open-angle glaucoma; SOAG = secondary open-angle glaucoma; VF= visual field.
