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

To investigate the characteristics of regenerated retinal pigment epithelial (RPE) cells after retinal laser photocoagulation in diabetic mice. C57BL/6J mice were used to induce diabetes using intraperitoneal injection of streptozotocin. The proliferation of RPE cells after laser photocoagulation was determined using the 5-ethynyl-2'-deoxyuridine (EdU) assay in both diabetic and wild-type mice. The morphological changes of RPE cells were evaluated by using Voronoi diagram from immunostaining for ß-catenin. Characteristics of regenerated cells were evaluated by quantifying the mRNA and protein levels of RPE and epithelial-mesenchymal transition (EMT) markers. There were significantly less EdU-positive cells in laser-treated areas in diabetic mice than wild-type mice. Hexagonality was extensively lost in diabetic mice. Many EdU-positive cells were co-localized with Otx2-positive cells in the center of the laser-treated areas in wild-type mice, but only EdU-positive cells were widely distributed in diabetic mice. Quantitative analysis of mRNA and protein levels showed that the expression levels of RPE markers, Pax6, Mitf, and Otx2, were significantly decreased in RPE of diabetic mice compared with that of wild-type mice, whereas the expression levels of EMT markers, vimentin and fibronectin, were significantly increased. The proliferation and hexagonality of regenerating RPE cells were impaired after laser photocoagulation, and the regenerated RPE cells lost their original properties in diabetic mice. Further clinical research is needed to elucidate the RPE response after laser photocoagulation in diabetic patients.
