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

purposeThis study aims to investigate the protective effects of luteolin on Müller cells under high glucose conditions and to elucidate its potential mechanisms of action.

methodsFirstly, Primary rat retinal Müller cells were divided into three groups: a control group (Control), a high glucose group (HG), and a high glucose plus luteolin group (HG + luteolin). To confirm that ferroptosis is indeed involved in cell death, cells were divided into another three groups: Control, HG), and high-glucose + Ferrostatin-1 (HG + Fer-1). Additionally, to further establish ferroptosis as the specific target of luteolin treatment, cells were divided into another three groups: Control, ferroptosis activator (RSL3), and RSL3 + luteolin group (RSL3 + luteolin). Cell apoptosis was assessed using flow cytometry and TUNEL staining. Intracellular levels of reactive oxygen species (ROS), malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione (GSH) were quantified with biochemical assay kits. Mitochondrial morphology was examined via transmission electron microscopy. The expression of ferroptosis-related factors xCT and GPX4 was evaluated through quantitative polymerase chain reaction and Western blotting.

resultsThe HG group showed increased apoptosis, ROS, MDA, mitochondrial damage and reduced levels of SOD, GSH, xCT and GPX14 compared to the control group. The HG + luteolin group reversed these effects, reducing apoptosis and oxidative stress while restoring mitochondrial health and increasing protective gene expression. Fer-1 inhibits high glucose-induced apoptosis and promotes cellular xCT and GPX4 protein expression. Luteolin inhibited RSL3-induced cellular iron apoptosis and promoted cellular xCT and GPX4 protein expression.

conclusionThe results demonstrate that high glucose levels induce ferroptosis in Müller cells. Conversely, luteolin intervention has been shown to alleviate high glucose-induced Müller cell damage by inhibiting cellular ferroptosis.
