The effectiveness and safety of one-stage iStent-based micro-invasive glaucoma surgery-A retrospective study.
Article in Frontiers in medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Purpose: Micro-invasive glaucoma surgery involves a group of treatment methods associated with a low rate of side effects and good effectiveness outcomes. One of the most frequently performed procedures belonging to this group is iStent microstent implantation. The aim of this study was to perform a retrospective evaluation of the safety and efficacy of a combined procedure involving cataract phacoemulsification and single iStent microstent implantation, performed simultaneously. Materials and methods: The complete medical records of 62 patients (91 eyes) were analyzed retrospectively, including the best corrected visual acuity, intraocular pressure, the mean defect of visual fields, and the number of active substances used in eye drops. The follow-up times were 1, 3, 6, 9, and 12 months after the surgical procedure. Results: A significant improvement in the best corrected visual acuity and a reduction of the intraocular pressure were achieved after the surgery. On average, after 12 months, the best corrected visual acuity improved from 0.70 (0.25) to 0.91 (0.18; Conclusion: Simultaneous cataract phacoemulsification with single iStent implantation in patients with open-angle glaucoma is a safe and effective method for reducing intraocular pressure and the number of topical medications that must be used. Having initially higher intraocular pressure values may limit the beneficial effects of iStent implantation by subordinating patients from topical treatment; thus, single iStent implantation may not be the most favorable choice in uncontrolled glaucoma cases.
