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
backgroundCorneal dystrophies are inherited disorders that can lead to significant visual impairment and often require surgical intervention in advanced stages. Fuchs endothelial corneal dystrophy (FECD) is the most frequently diagnosed type in Western countries and remains a leading global indication for corneal transplantation. In contrast, non-Fuchs dystrophies represent a diverse group of less common entities, each with distinct clinical features, surgical considerations, and regional variations in incidence and management. Despite their relevance, long-term data on the full spectrum of corneal dystrophies remain scarce. This study aimed to evaluate the distribution and temporal trends in dystrophy types and associated surgical procedures over eight decades at a tertiary referral center in Germany.
methodsThis retrospective analysis included 3 827 histopathologically confirmed corneal dystrophy specimens identified from an archive of 58 150 ophthalmic specimens collected between 1945 and 2024. Extracted data included dystrophy type, patient age at surgery, sex assigned at birth and associated surgical procedures. Distribution and temporal trends were analyzed descriptively.
resultsFECD accounted for 90.3% (n = 3 455) of all cases, with a more than 15-fold increase in annual cases between 2003 and 2024. Its surgical management transitioned from exclusive use of penetrating keratoplasty (PKP) to posterior lamellar keratoplasty in over 99% of cases by 2024. Among non-Fuchs dystrophies (n = 372), granular (21.2%), macular (17.5%), and lattice dystrophy (17.2%) were most frequent. These exhibited greater surgical variability, reflecting their heterogeneity across 21 non-Fuchs dystrophy types in this study. Stromal and epithelial-stromal dystrophies were predominantly managed with PKP, whereas superficial epithelial and basement membrane dystrophies were increasingly treated with phototherapeutic or manual superficial keratectomy. Limbo-keratoplasty was introduced in the early 2000s for recurrent subepithelial and epithelial-stromal types.
conclusionThis study provides unique insights into the type distribution and surgical management of corneal dystrophies over eight decades in a German center, encompassing nearly all IC3D-classified entities. The marked increase in FECD specimen numbers and the shift toward lamellar keratoplasty reflect evolving clinical practices and rising demand on corneal transplantation services. The broader clinical spectrum and procedural diversity among non-Fuchs dystrophies underscore the ongoing need for pathology-specific management strategies tailored to population-specific needs.
