Patient referral flow between physician and ophthalmologist visits for diabetic retinopathy screening among Japanese patients with diabetes: A retrospective cross-sectional cohort study using the National Database.
Article in Journal of diabetes investigation, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
AIMS/
introductionRegular screening for diabetic retinopathy is essential. This study aimed to show the process and current situation of diabetic retinopathy screening prescribed by physicians (internists) and ophthalmologists for Japanese patients with diabetes. MATERIALS AND
methodsThis retrospective cohort study used data from the Japanese National Database of Insurance Claims between April 2016 and March 2018. Ophthalmology visits and fundus examinations are defined using specific medical procedure codes. The proportion of ophthalmology visits for patients with diabetic medication and for fundus examination among those who visited ophthalmologists was calculated in the fiscal year 2017. A modified Poisson regression analysis was carried out to identify factors associated with retinopathy screening. Similarly, quality indicators by prefectures were also calculated.
resultsAmong 4,408,585 patients receiving diabetic medications (57.8% men, 14.1% insulin use), 47.4% visited the ophthalmology department and 96.9% of those underwent fundus examination. Regression analysis showed that female sex, older age, insulin use, medical facilities with Japan Diabetes Society certification and large medical facilities were predictors of fundus examination. By prefecture, the ophthalmology consultation rate and the fundus examination ranged 38.5-51.0% and 92.1-98.7%, respectively.
conclusionsLess than half of the patients who were prescribed antidiabetic medication by their physicians visited an ophthalmologist. However, most of the patients who visited an ophthalmologist had a fundus examination carried out. A similar tendency was noted for each prefecture. It is essential to reaffirm the necessity of recommending ophthalmologic examinations to physicians and healthcare professionals who care for patients with diabetes.
