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: This study compared clinical outcomes of toric intraocular collamer lens (TICL) implantation for myopia and astigmatism correction using image-guided navigation versus manual astigmatic marker alignment, evaluating postoperative astigmatism correction accuracy. Methods: A retrospective analysis included 250 patients (467 eyes) undergoing TICL implantation between January and June 2023. Patients were divided into manual (slit-lamp axis marking) and image-guided (navigation-adjusted lens positioning) groups. Preoperative parameters were comparable. Postoperative visual acuity, refraction, and astigmatism vector analysis (TIA, SIA, DV, CI, AE) were assessed at 3 months. Results: No significant differences were observed in preoperative parameters, postoperative spherical equivalent (SE), or corrected distance visual acuity (CDVA) ( Conclusion: Image-guided TICL implantation yielded superior visual outcomes and greater astigmatism correction accuracy compared to manual marking, with no complications reported. This highlights the clinical advantage of navigation systems in optimizing refractive precision.
