Ginkgolide B protects retinal pigment epithelial cells from H

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
Objective: To investigate whether Ginkgolide B (GB) protects retinal pigment epithelial cells (RPEs) from hydrogen peroxide (H Methods: Human RPEs were divided into the following groups: control, model (200 μmol/L H₂O₂ for 24 h), GB + H₂O₂, GB + H₂O₂ + Compound C (an AMPK inhibitor), H₂O₂ + Compound C, and GB alone. Cell viability, apoptosis, antioxidant parameters, and AMPKα/Nrf2 expression were assessed using the Cell Counting Kit-8 (CCK-8) assay, flow cytometry, colorimetric biochemical assays, transmission electron microscopy (TEM), quantitative polymerase chain reaction (PCR), and Western blot. Results: TEM showed that GB attenuated H₂O₂-induced mitochondrial swelling and cristae disruption, which were reversed by Compound C. Compared with the model group, the GB + H₂O₂ group exhibited increased cell viability, decreased apoptosis, elevated activities of catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD), as well as increased glutathione (GSH) content, and reduced malondialdehyde (MDA) (all Conclusion: GB was associated with protection of RPEs against H₂O₂-induced oxidative stress and apoptosis. Because these protective effects were attenuated by pharmacological inhibition of AMPK, the findings suggest that AMPK/Nrf2 signaling may contribute to the cytoprotective actions of GB. However, additional mechanistic studies are required to confirm the involvement of this pathway.
