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: Oxidative stress plays a crucial role in the pathogenesis of periodontitis and compromises the regenerative potential of human periodontal ligament stem cells (hPDLSCs). Astaxanthin (ASX), a potent natural antioxidant with both lipophilic and hydrophilic properties, has been shown to scavenge reactive oxygen species (ROS). However, its protective effects on hPDLSCs under oxidative stress remain largely unexplored. Methods: hPDLSCs were isolated and characterized. An oxidative stress model was established by exposing cells to 300 μM H Results: ASX significantly reduced intracellular and mitochondrial ROS levels, preserved mitochondrial membrane potential, and inhibited H Conclusion: These findings demonstrate that ASX ameliorates oxidative stress-induced injury in hPDLSCs via the Nrf2/ARE signaling pathway, exerting antioxidative, anti-inflammatory, and pro-osteogenic effects. This suggests its therapeutic potential for promoting periodontal regeneration under oxidative microenvironments.
