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

To investigate early changes of iris vasculature in type 2 diabetes mellitus (T2DM) patients without diabetic retinopathy (DR) using anterior segment optical coherence tomography angiography (AS-OCTA), and evaluate potential predictors associated with iris vasculature in this population. This was a cross-sectional study. T2DM patients and healthy controls were patients who visited the Department of Ophthalmology at the Affiliated Hospital of Yangzhou University. Iris vessel density (IVD) was quantified using AS-OCTA (YG-100KPRO, TowardPi Medical Technology, Beijing, China). IVD was also performed in the whole and four quadrant sectors of iris, that is nasal superior (NS), nasal inferior (NI), temporal superior (TS), and temporal inferior (TI) sectors. Thirty-six patients with T2DM and thirty-nine healthy controls were recruited in this study. IVD in T2DM patients was lower than in healthy groups, particularly in the whole iris (P = 0.016) and the NI (P = 0.022) and TI (P = 0.007) sectors of the iris. Male gender was a positive independent predictor of IVD, whereas body mass index and blood glucose were negative independent predictors of IVD. AS-OCTA provides a reliable method to quantify iris blood flow. Our study reveals the deterioration of the iris vascular system in patients with T2DM, even without DR. These findings highlight the significance of iris blood flow parameters in T2DM patients, which could be helpful in follow-up studies and future screening for ocular vascular diseases associated with T2DM.
