Prevalence of diabetes and diabetic retinopathy among adults aged 50 years and above in Nepal: a population-based cross-sectional survey.
Article in BMJ open ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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), a microvascular complication of diabetes mellitus (DM), is a leading cause of vision loss worldwide. There is limited national data to inform about the prevalence of DM and DR and its associated factors, which led to the basis of conducting this survey, which would guide us for the same as part of the Rapid Assessment of Avoidable Blindness (RAAB) survey conducted across Nepal.
methodsA population-based cross-sectional RAAB survey was conducted using multistage cluster random sampling. RAAB+DR methodology was conducted between June 2019 and February 2021 among individuals aged≥50 years across selected provinces. Diabetes was diagnosed based on treatment history and random blood glucose test with level>200 mg/dL, while DR was graded by trained ophthalmologists. All relevant data were imported into the RAAB software to determine the prevalence of DM, DR and associated factors.
resultsAmong the 13 510 participants examined, the prevalence of DM was found to be 6.1% which was higher in Bagmati province at 9.4% (95% CI: 8.2% to 10.7%). Prevalence of DM was higher among females, but DR was more common in males in rural areas and females in urban areas. Untreated diabetes was most common in Madhesh (35.1%). DR prevalence was highest in Bagmati (15.9%; 95% CI: 12.7% to 19.1%), and 2.5% (95% CI: 1.2% to 3.8%) of those patients had sight-threatening DR. In Bagmati, 24.1% of diabetics had never undergone an eye examination.
conclusionThe limited coverage of DR screening underscores the need for enhanced community-based DR screening and referral programmes. Our study lacked the use of plasma blood glucose level measurement to diagnose DM, proper slit lamp examination for diabetic retinopathy grading and diagnosis, and inclusion of a younger population providing a better representation. Strengthening these initiatives can prevent vision-threatening complications in underserved populations.
