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: Vitamin A deficiency (VAD) has been shown to be associated with diabetic retinopathy (DR). However, only a small number of studies have examined the association between VAD and DR in patients with type 2 diabetes (T2DM). The aim of this study was therefore to determine the association between serum vitamin A level and DR in T2DM patients. Methods: From 2019 to 2024, information was retrospectively collected on 470 healthy controls and 1020 patients with T2DM (500 without DR and 520 with DR). Inclusion criteria included those older than 30 years and having undergone retinal examinations for DR severity grading and measurement of serum vitamin A level. Results: Of the total participants, 44.03% had a deficient serum vitamin A level (<1.0 μmol/L). Vitamin A level in patients with DR was significantly reduced compared to those in healthy controls ( Conclusion: This study suggests that low serum levels of vitamin A correlate with the presence and severity of DR. VAD may therefore represent a potential biological vulnerability for DR.
