1 · What the graph read from it

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.

2 · The registry

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

Corneal alkali burns can cause persistent inflammation and corneal neovascularization. In this study, we divided corneal alkali burned rabbits into the untreated group, the blank lens group, the radiation-treated umbilical cord mesenchymal stem cells (UCMSC) lens group, and the UCMSC I.V. group, and then measured corneal inflammation, neovascularization and corneal injury repair via slit lamp microscopy, captured anterior segment optical coherence tomography (AS-OCT), and performed hematoxylin-eosin staining. Compared with those in the other experimental groups, radiation-treated UCMSC lenses significantly decreased inflammatory index (IF) scores, areas of corneal blood vessels and corneal epithelial injury. The expression of interleukin (IL)-17 in corneas treated with radiation-treated UCMSC lenses was lower than that in corneas treated with blank lenses, and radiation-treated UCMSC lenses exhibited greater expression of IL-4 and signal transducer and activator of transcription 1 (STAT1), while the expression of cluster of differentiation-3G (CD3G), a linker for the activation of T cells (LAT), IL-6, IL-1B, CC chemokine receptor 6 (CCR6) and IL-23 exhibited the opposite effects (all P < 0.05). Our findings demonstrated that irradiated UCMSC-coated high oxygen-permeable hydrogel lenses on the ocular surface inhibited corneal angiogenesis and inflammation after corneal alkaline burns. The downregulation of Th17 cell differentiation might be responsible for these effects.
