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

backgroundCorneal dystrophy is a group of hereditary disorders with different presentations and management between regions and ethnic groups. This study aimed to report the patterns of corneal dystrophy, the frequency of keratoplasty requirement, and the outcomes of performed keratoplasty among cases with corneal dystrophy at a tertiary eye hospital in Nepal.

methodsData of all patients presented at corneal clinic, Tilganga Institute of Ophthalmology, with the diagnosis of corneal dystrophy documented in the Electronic Medical Record (EMR) from 1st January 2017 to 31st December 2025 were identified, categorized, and analyzed regarding demographic status, corneal dystrophic subtypes, the needs for keratoplasty, and the outcomes of the keratoplasty performed.

resultsAmong 264 eyes of 132 participants, 50.8% and 49.2% were male and female, respectively. The mean age ± standard deviation of the participants was 43.7 ± 20.5 years. Epithelial-subepithelial, stromal, and endothelial dystrophy accounted for 9.8%, 21.3%, and 63.6%, respectively. Fuchs endothelial corneal dystrophy (FECD) was the most common subtype, followed by congenital hereditary endothelial dystrophy (CHED) and epithelial basement membrane dystrophy (EBMD). In 264 eyes of 132 patients, 92 eyes (34.9%) were indicated for keratoplasty. The proportion of eyes requiring keratoplasty were 34.8%, 29.3%, 31.5%, and 4.3% in FECD, CHED, the stromal dystrophy group, and unspecified corneal dystrophy, respectively. Among the eyes that underwent keratoplasty, 71.4% had clear graft at the l2-month follow-up visit.

conclusionFuchs Endothelial Corneal Dystrophy was the most common subtype of corneal dystrophies in the current study. However, the proportion of FECD cases requiring keratoplasty was significantly lower than that in CHED and the stromal dystrophy group. Outcomes of keratoplasty were satisfactory, as a large number of cases had clear grafts at the12-month visit.
