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
Doxycycline (Dxy), a broad-spectrum antibiotic with anti-inflammatory effects, is commonly used in ophthalmology but is unstable as a topical eyedrop, degrading quickly into inactive forms and requiring frequent application. To address this, gelatin nanoparticles (GNPs) loaded with Dxy (DNPs) were developed as a stable ophthalmic nanomedicine for enhancing corneal wound healing by inhibiting matrix metalloproteinases (MMPs). In this study, female Sprague-Dawley rats underwent lamellar keratectomy, and various Dxy formulations-oral, conventional eyedrops, and DNP-containing eyedrops-were evaluated for corneal wound repair. Clinical assessments included fluorescein staining, slit-lamp biomicroscopy, spectral-domain optical coherence tomography (SD-OCT) imaging, histopathology, and immunohistochemistry for MMP-2, MMP-9, and α-SMA. The DNP group (0.01% Dxy in DNPs, applied twice daily) demonstrated faster corneal thickness recovery and epithelial healing on days 7 and 14 compared to 0.1% Dxy eyedrop treatments applied twice or four times daily. DNP-treated eyes also showed reduced angiogenesis intensity and lower MMP-2 and MMP-9 immunoreactive scores, with enhanced stromal recovery and reduced neovascularization. These results highlight DNPs' potential as a superior treatment for corneal wounds, providing effective healing with less frequent dosing and lower drug concentrations. This study supports DNPs' potential for clinical application as a stable and efficient therapeutic agent in ophthalmology.
