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
Perioperative neurocognitive disorders (PNDs) represent a significant challenge in the perioperative setting, while the pathophysiology of PNDs remains unclear. Utilizing a murine model of abdominal surgery, we found that abnormal glutamatergic neurotransmission in the medial prefrontal cortex (mPFC) and hippocampus contributes to postoperative cognitive impairments. Increases in the frequency of miniature excitatory postsynaptic currents in both the mPFC and CA1 neurons indicate enhanced presynaptic glutamate release while having little effect on inhibitory neurotransmission. Surgery also enhances glutamate release from presynaptic terminals in the Schaffer collateral pathway. In addition, abdominal surgery increased the activation of microglia and astrocytes, elevated central inflammatory markers, and reduced excitatory amino-acid transporter-2 expression. Dexmedetomidine significantly mitigates the postoperative cognitive deficits by reducing inflammation and preserving neuronal structural complexity and dendritic spine stability, likely through inhibiting glutamate release and enhancing its reuptake. These findings advance our understanding of the etiology of PNDs and provide hints for potential intervention.
