Postoperative complications after cataract surgery with and without concurrent minimally invasive glaucoma surgery in patients with primary open angle glaucoma: a comparative risk analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Primary open-angle glaucoma (POAG) is the most common form of glaucoma and a leading cause of irreversible blindness worldwide. Treatment focuses on lowering intraocular pressure (IOP), often through cataract extraction with intraocular lens implantation (CE/IOL) alone or combined with minimally invasive glaucoma surgery (MIGS). However, comparative postoperative complication risks between these approaches remain unclear. Methods: This retrospective cohort study utilized the TriNetX US Collaborative Network to identify all adults (ages ≥18 years) with a diagnosis of POAG who underwent CE/IOL with or without concurrent MIGS between 2006 and 2026. The cumulative postoperative incidence of hyphema, cystoid macular edema (CME), retinal detachment (RD), and endophthalmitis were evaluated at four time intervals up to 90 days postoperatively. Propensity score matching was used to balance baseline characteristics and reduce confounding. Outcomes were compared using relative risks with 95% confidence intervals, and Results: After propensity score matching, each routine cataract surgery cohort (with and without MIGS) comprised 7, 998 patients. Patients undergoing CE/IOL with MIGS had a significantly higher rate of hyphema compared with patients undergoing CE/IOL alone at all reported postoperative time points, with a cumulative incidence of 1.19% versus 0.15% at 1-90 days after surgery, respectively (P<0.0001). Conversely, the cumulative incidence of CME (2.585% vs 2.376%, Conclusions: In this large retrospective cohort study, combined CE/IOL with MIGS was associated with a significantly increased risk of postoperative hyphema, while rates of CME, RD, and endophthalmitis remained comparable to CE/IOL alone.
