Article in Biomolecules, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Astrocytic function imbalance is a key factor affecting cerebral ischemia rehabilitation. Mesenchymal stem cells have therapeutic potential for cerebral ischemia, but their mechanisms remain unclear. This study explored how placental mesenchymal stem cells pro-mote astrocytes towards the A2 phenotype, which benefits the repair of cerebral ischemia injury. We established the animal model of middle cerebral artery ischemia/reperfusion and an in vitro interleukin-1β-treated astrocyte inflammation model and utilized neuro-logical function assessment, 2,3,5-triphenyltetrazolium chloride staining, immunofluorescence staining, Western blotting and other methods to evaluate the impact and associated mechanisms of transplanting placental mesenchymal stem cells into rats with cerebral ischemia-reperfusion injuries. The results demonstrated that transplantation of placental mesenchymal stem cells ameliorated neurological dysfunction and histopathological damage, alleviated neuroinflammation and enhanced neurotrophic factor levels, promoted the polarization of interleukin-1β-treated astrocytes toward the A2 phenotype, and suppressed the abundance of core mediators within the cerebral TGF β1/Smad signaling cascade in ischemia/reperfusion model. Collectively, placental mesenchymal stem cell grafting facilitates the polarization of cerebral astrocytes toward the protective A2 phenotype, presumably by regulating the TGF β1/Smad signaling cascade in ischemic brain injury.
