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 disorder (PND) is the mild cognitive impairment associated with surgery and anesthesia. It is a common surgical complication in the elderly. An important mechanism of PND is the surgically induced neuroinflammation. The interaction between the neuronal surface protein CD200 and its receptor in microglia, CD200R1, is an important regulatory pathway to control neuroinflammation. However, the potential role of the CD200-CD200R1 pathway in the acute period of PND has not been fully investigated. In this study, in a PND mouse model, we first measured the protein expression level of CD200, CD200R1, and the related pro- and anti-inflammatory cytokines in the hippocampus. Then, we investigated cognitive function, neuroinflammation and postsynaptic density protein 95 (PSD-95) expression after the injection of CD200-Fc (agonist), CD200R1-Fc (antagonist) or IgG1-Fc (vehicle) into lateral ventricle in PND models. Compared with the control group, the expression of CD200 was up-regulated at day 1 after surgery in PND models. The injection of the CD200-Fc into the lateral ventricle could mitigate primed neuroinflammation and cognitive decline, increase the expression of PSD-95 at day 1 after surgery in PND models. In conclusion, we have demonstrated that CD200-CD200R1 signaling was involved in the acute inflammatory process of PND, and activating CD200R1 can inhibit neuroinflammation and attenuate PND. Thus, the CD200-CD200R1 axis is a potential novel target for PND prevention and treatment.
