Ex vivo transfer of Smad7 decreases damage to the corneal endothelium after penetrating keratoplasty.
Article in Japanese journal of ophthalmology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeTo determine whether transient gene transfer and expression of the intracellular antagonist of transforming growth factor beta (TGF-beta), Smad7, to corneal endothelial cells decreases corneal endothelial cell damage after penetrating keratoplasty in a rabbit model.
methodsRabbit corneas were transfected ex vivo with replication-deficient adenoviruses encoding Flag-tagged Smad7, Flag-tagged Smad3, or LacZ (termed AdCMV-Smad7, AdCMV-Smad3, AdCMV-LacZ) and then transplanted to normal rabbits. Expression of the exogenous Smads and phosphorylation of endogenous Smad2 in the transplanted corneal endothelium were examined by immunoblotting and immunohistochemistry with anti-Flag or anti-phosphorylated Smad2 antibodies. Cellular density and morphological changes in the corneal endothelium of the transplanted cornea were evaluated by scanning electron microscopy after transplantation of the Smad-transfected corneas.
resultsTransplanted AdCMV-Smad7-transfected corneas significantly inhibited the decrease in cellular density and accelerated wound healing at the host-graft junction when compared with transplanted AdCMV-LacZ-transfected corneas. Transplanted AdCMV-Smad3-transfected corneas showed decreased cellular density and delayed wound healing at the host-graft junction.
conclusionsEx vivo gene transfer of Smad7 to corneal endothelial cells inhibits the decrease in cellular density and accelerates wound healing after penetrating keratoplasty in rabbits. Thus, modulation of Smad7 expression in corneal endothelial cells may decrease corneal endothelial cell damage after penetrating keratoplasty.
