Determinants of diagnostic yield in a multi-ethnic Asian inherited retinal disease cohort.
Article in European journal of human genetics : EJHG, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
As the discovery of new genes causing inherited retinal disease (IRD) has plateaued, we look to other factors which could be used to maximize diagnostic yield. We analyzed whole-exome sequencing (WES) data from 506 IRD probands, focusing on the interplay between diagnostic yield, age of symptom onset or diagnosis, family history, and initial clinical diagnosis. The cohort's overall diagnostic yield was 49.2%. Diagnostic yield was negatively correlated with the age of symptom onset and positively correlated with the number of affected family members. Diseases with distinctive clinical presentations such as Bietti crystalline dystrophy (BCD) or Leber congenital amaurosis (LCA) were more reliably diagnosed than more common and heterogeneous diseases like retinitis pigmentosa (RP) and cone-rod dystrophy (CRD). Recurrent genes and variants in this Chinese-majority cohort resemble those found in Chinese cohort studies but differ from populations of European descent, with implications for the design and prioritization of gene therapies. These insights may help optimize the diagnostic utility of genetic testing for IRDs, enhance the delivery of genetic counseling for patients, and guide the development of more inclusive targeted therapies.
