National Survey on Corneal Transplantation in Japan.
Article in Cornea, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 report the results of a national survey on corneal transplantation in Japan.
methodsThe Japan Cornea Society and the Keratoplasty Society of Japan conducted a national survey on corneal transplantation performed from 2017 to 2019. Data from various institutions were collected through an online database and subsequently analyzed.
resultsIn total, 4951 cases from 44 facilities were documented. The leading cause of corneal transplantation was corneal edema (CE), which accounted for 39.3% of cases, followed by repeat keratoplasty at 27.7%. Among CE cases, postcataract surgery was the most prevalent (25.1%), followed by postglaucoma surgery (20.8%) and laser iridotomy-induced CE (18.2%). Fuchs endothelial corneal dystrophy was the fourth most common cause (10.9%). Regarding surgical methods, Descemet stripping automated endothelial keratoplasty was the most common, used in 41.3% of procedures, followed by penetrating keratoplasty at 37.1%. Deep anterior lamellar keratoplasty and Descemet membrane endothelial keratoplasty were used in 8.1% and 2.6% of cases, respectively. One year after transplantation, graft clarity was maintained in 80.5% of cases, and regrafting was necessary in 15.2% of instances.
conclusionsThe national survey reveals that CE is the most frequent indication for corneal transplantation in Japan. Increases in cases from glaucoma surgery and Fuchs endothelial corneal dystrophy were noted among patients with CE. Endothelial keratoplasty, especially Descemet stripping automated endothelial keratoplasty, is now the preferred surgical technique for these transplants.
