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

purposeWe clarified the effects of an ophthalmic solution of a peroxisome proliferator-activated receptor gamma (PPARγ) agonist on corneal inflammation and wound healing after alkali burn injury in rats.

methodsAfter alkali exposure, either an ophthalmic solution with 0.1% pioglitazone hydrochloride (the PPARγ group) or vehicle (the vehicle group) was topically applied to the cornea until day 14. Histological, immunohistochemical, and real-time reverse transcription polymerase chain reaction analysis were performed.

resultsAfter alkali injury, PPARγ expression increased, with the infiltration of many inflammatory cells. The infiltration of neutrophils and macrophages started from the corneal limbus within 6 h, and developed in the corneal center by day 7, with associated neovascularization. The accumulation of α-smooth muscle actin-positive myofibroblasts and the deposition of type III collagen were noted on day 14. The histological changes were suppressed significantly by treatment with the ophthalmic solution of the PPARγ agonist. In addition, the number of infiltrating M2 macrophages in the cornea was increased by PPARγ agonist treatment. In real-time reverse transcription polymerase chain reaction analysis, the messenger ribonucleic acid expression levels of interleukin-1β (IL-1β), IL-6, IL-8, monocyte chemoattractant protein-1, tumor necrosis factor-α, transforming growth factor beta 1, and vascular endothelial growth factor-A were decreased in the PPARγ group compared to the vehicle group in the early periods of corneal inflammation.

conclusionsThe ophthalmic solution of the PPARγ agonist inhibited inflammation, decreased the fibrotic reaction, and prevented neovascularization in the cornea from the early phase after alkali burn injury. The ophthalmic solution of the PPARγ agonist may provide a new treatment strategy with useful clinical applications for corneal inflammation and wound healing.
