Polygenic risk score for predicting diabetic retinopathy in patients with type 2 diabetes: A twenty-year follow-up study.
Article in World journal of diabetes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDiabetic retinopathy (DR) is the leading cause of blindness among working-age adults, with an increasing prevalence due to the global burden of diabetes.
aimTo develop a polygenic risk score (PRS) to identify high-risk groups for DR and evaluate its severity in patients with type 2 diabetes (T2D).
methodsThis population-based study included 13335 patients with T2D, comprising 7295 patients with DR and 6040 without DR. Genetic data, duration of DR diagnosis, body mass index, systolic blood pressure, diastolic blood pressure, and glycated hemoglobin A1c levels were obtained from the study population. The PRS was constructed from a genome-wide association study conducted in a Taiwanese Han population. Electronic medical records were used to track patients with T2D and analyze the associations between PRS, timing of DR diagnosis, and therapeutic interventions. The hazard ratio (HR) of PRS for DR development and severity was estimated using multivariate Cox proportional hazards regression.
resultsThe results demonstrated that patients with T2D in the top PRS decile had a 1.21-fold greater risk of developing DR [HR = 1.21; 95% confidence interval (CI): 1.01-1.45;
conclusionPatients with T2D with a higher PRS are at increased risk of developing DR and may experience more severe forms of the disease.
