1 · What the graph read from it

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.

2 · The registry

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

objectiveTo assess the efficacy of XEN gel stent implantation combined with mitomycin C (MMC) injection in controlling intraocular pressure (IOP) and the dosage of postoperative medication for open-angle glaucoma (OAG) patients.

methodsThe PubMed, Embase, Cochrane Library, and Science Direct databases were searched from inception to August 2022 without any language restriction. All studies that compared IOP and the dose of medication before and after XEN gel stent implantation and MMC injection for OAG patients were included. Data extraction and methodological quality evaluation were performed.

resultsA total of 26 studies (2329 eyes) were involved in meta-analysis. It was revealed that IOP at 1 month after XEN implantation was significantly lower than preoperative IOP [group 1, IOP between 19.2 and 21.2 mmHg: mean difference (MD) = 7.60, 95% confidence interval (CI) [6.55, 8.66], I

conclusionXEN implantation combined with MMC injection significantly decreased IOP in OAG patients at 1, 6, 9, 12, and 24 months after treatment. In addition, XEN implantation combined with MMC injection decreased the amount of medication used at 6, 12, and 24 months after treatment in OAG patients.
