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: The study aims to evaluate the efficacy and safety of a novel Triangle Suture Technique in the surgical placement of Scleral-Fixated Intraocular Lenses (SFIOLs). The research seeks to address the challenges in cases associated with inadequate capsular support for Intraocular Lens (IOL) implantation, offering an alternative to traditional methods. Methods: This A pilot retrospective case series evaluated the efficacy and safety of a novel Triangle Suture Technique for scleral-fixation of intraocular lenses (SFIOL) using 10-0 Polypropylene suture (Prolene; Ethicon, Inc) in patients with dislocated IOLs. Visual acuity outcomes, intraocular pressure control, and post-operative complications were assessed. Results: The study comprised 52 eyes from 49 patients (mean age 80.3±10.3 years). Mean pre-operative uncorrected visual acuity (UCVA) significantly improved from 1.14±0.84 to 0.61±0.56 logMAR at 3 months (P=0.001). Best-corrected visual acuity (BCVA) also improved from 0.84±0.65 to 0.54±0.56 logMAR at 3 months (P=0.048). Glaucoma drop usage decreased from 0.67±1.09 to 0.25±0.62 types at 6 months (P=0.018). Peri-operative complications included anterior segment complications in 4 eyes (7.54%) and posterior segment complications in 1 eye (1.9%). While non-recurrent IOL dislocation occurred in 45 eyes (86.5%), recurrent dislocation was noted in 7 eyes (13.5%), with one eye experiencing twice recurrent dislocation (1.9%). Conclusion: The triangle suture technique is a versatile and accessible option for scleral fixation of various IOL designs. While these preliminary results demonstrate anatomical efficacy, the study's retrospective nature, small cohort, and single-surgeon experience necessitate a cautious interpretation. Further large-scale, comparative studies are required to establish long-term stability and clinical efficacy relative to current gold-standard methods.
