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
Astrocytes critically regulate states of consciousness, yet their molecular profiles across wake, sleep, and general anesthesia remain unclear. This study conducted proteomic and phosphoproteomic analyses of rat cortical astrocytes across these states using sevoflurane. Data quality was validated using principal component analysis (PCA) and Pearson correlation coefficient (PCC). Proteomics showed state-specific signatures: sleep and anesthesia shared similar changes (downregulated structural proteins, upregulated membrane transport complexes) but diverged in molecular expression. Anesthesia specifically suggested potential activation of cellular differentiation/structural plasticity-related pathways but implied potential disruption of metabolism and molecular clearance processes compared to sleep. Phosphoproteomics revealed the unique phosphorylation changes during general anesthesia compared to wake and normal sleep: downregulated phosphorylation of nuclear casein kinase and cyclin-dependent kinase substrate 1 (NUCKS1) at Ser188, suggesting the potential suppression of nuclear transcription and/or cell cycle activity, which may act as a potential molecular signature associated with the anesthetic state. Clustering analysis showed that sleep was associated with upregulated mRNA processing, while anesthesia indicated potential enhancement of synaptic signaling and suggested possible suppression of development-related programs. In summary, astrocytes undergo extensive molecular reprogramming during transitions of consciousness; while they share common features in morphological remodeling, sleep and anesthesia differ fundamentally in astrocytic molecular outcomes, offering new insights into astrocytic roles in unconsciousness.
