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: To present a modified technique of 4-point scleral fixation using polymethyl methacrylate (PMMA) 2 eyelets intraocular lens (IOL) with 8-0 polypropylene sutures. Methods: A 270-degree conjunctival peritomy is done, and 4 sclerotomies (2 nasal and 2 temporal) are created. Lamellar scleral or clear corneal incision is made at superior site (6 mm wide for sclera or 5.5-6 mm for corneal). A short segment of 8-0 polypropylene is inserted into each eyelet, each thread of the suture is externalized through the sclerotomy site, and the lens is inserted. The suture is tightened evenly, and the knot is rotated and internalized. Scleral incision and conjunctival peritomy are sutured with 8-0 vicryl. Results: We have performed this technique in 6 patients with excellent visual outcomes and no reported complications over 1 year of follow-up. This technique has practical advantages including rigid and stable PMMA IOL, high tensile, and slim 8-0 polypropylene suture which is easily internalized and less irritated, and affordable and widely available overall consumables. Conclusion: We present a modified 4-point scleral fixation technique for posterior chamber IOL placement using PMMA IOL with 2 eyelets and 8-0 polypropylene as compared to previous studies that used foldable IOL with 4 eyelets and 10-0 polypropylene or Gore-Tex sutures. This procedure has moderate technical complexity, comparable to previously reported techniques with good overall clinical outcomes and several practical advantages, particularly related to the affordability and availability of the consumables.
