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
Lipid keratopathy is an uncommon corneal disorder characterized by stromal lipid deposition that may cause progressive corneal opacity and visual impairment. We report a case of advanced bilateral lipid keratopathy with severe visual-axis involvement. At presentation, best-corrected visual acuity (BCVA) was counting fingers in the right eye and 0.1 Snellen (1.0 logMAR) in the left eye. Slit-lamp examination and anterior segment optical coherence tomography (AS-OCT) demonstrated dense stromal lipid deposits involving the visual axis in both eyes. The patient underwent staged bilateral penetrating keratoplasty, with procedures performed three months apart. Postoperatively, corneal transparency improved in both eyes. At 6 months, BCVA was 0.5 Snellen (0.3 logMAR) in the right eye and 0.7 Snellen (0.15 logMAR) in the left eye. Residual visual limitation was attributed mainly to coexisting cataract, and sequential cataract surgery was planned. Together, the clinical photographs and AS-OCT scans illustrate an uncommon presentation of visually disabling bilateral lipid keratopathy, characterized by dense central stromal lipid deposition involving both visual axes and profound preoperative visual loss. The case is clinically noteworthy because it combines severe bilateral disease, close clinical-tomographic correlation, and sequential penetrating keratoplasty performed as a staged visual rehabilitation strategy, resulting in restoration of graft clarity and meaningful visual improvement during postoperative follow-up.
