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
This study aims to investigate the efficacy of glueless simple oral mucosal transplantation to prevent the development of the limbal stem cell deficiency in rabbit model. Rabbit limbal stem cell deficiency (LSCD) models were constructed with alcohol and mechanical scraping. The oral mucosa and limbal tissue were harvested and cut into small pieces. Microincisions were made on the corneal limbus and the precut pieces were inserted in. Animals were divided to three groups: glueless simple oral mucosal epithelium transplantation (GSOMT), glueless simple limbal epithelium transplantation (GSLET) and LSCD group. Corneal epithelium defects, opacity and neovascularization were observed after surgery by slit-lamp microscopy. Neovascularization and epithelialization were scored. HE staining and immunohistochemistry of CK12, CK13, p63 were performed after observation. In the LSCD group, corneal neovascularization and opacification were present and epithelial defects were still observed by 4 months. In the GSOMT group, the cornea was clear and epithelialization was complete by 15 days; the fluorescein staining scores and neovascularization were significantly lower in GSOMT group comparing with LSCD group. There were no significant differences between GSOMT group and GSLET group. Histological study showed that the transplanted oral mucosal graft blend into the recipient corneal tissue well after surgery and the morphology or phenotype of the corneal epithelium surrounding the graft were similar to that of normal corneal epithelium. The glueless simple oral mucosal transplantation successfully prevented the development of the limbal stem cell deficiency in rabbit model. This method avoids the limited graft sources and the allogeneic rejection problem especially in binocular LSCDs. GSOMT could become a new surgery method for treating LSCD and this basic research lays a foundation for next clinical promotion and application.
