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

Background: Diabetic kidney disease (DKD) and diabetic retinopathy (DR) represent two major microvascular complications of diabetes mellitus (DM). Previous studies have suggested that renin-angiotensin system inhibitors (RASi) exert protective effects on both DKD and DR. However, their specific impact on retinal microvascular parameters (RMPs), as well as the association between changes in fundus microvasculature and alterations in renal clinical parameters, remains unclear. This pilot study aimed to quantitatively assess the short-term effects of RASi on retinal microvasculature in patients with DKD using an artificial intelligence (AI)-based analysis of ultra-wide-field (UWF) fundus images. Methods: In this prospective cohort study, 27 patients with DKD were enrolled between July 2023 and September 2024. UWF fundus images were acquired at baseline and 12 weeks after initiation of RASi therapy. A validated deep learning AI model was employed to segment retinal vessels and quantify RMPs, including fractal dimension (D Results: Among the enrolled patients, 21 patients (77.8%) were male, with a mean age of 55.7 ± 14.2 years, a mean diabetes duration of 9.9 ± 6.6 years, a baseline estimated glomerular filtration rate (eGFR) of 73.7 ± 18.5 mL/min/1.73 m², and a median proteinuria of 0.57 (0.25, 0.97) g/24h. Fifteen patients (55.6%) had diabetic retinopathy (DR). After 12 weeks of RASi treatment, significant decreases were observed within the UWF images in venous D Conclusion: RASi therapy might be associated with retinal peripheral venous alterations, providing clues to a vascular- and topography-specific therapeutic response and shedding light on a potential imaging biomarker for diabetes management.
