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
The impact of general anesthetics on neurodevelopment is highly controversial in terms of clinical and preclinical studies. Evidence mounted in recent years indicated development of social cognitions was more susceptible to general anesthesia in early life. However, the behavioral characterization during adolescence and underlying mechanisms remains unclear. Herein, we observed that early postnatal S-ketamine exposure specifically induced deficits in sociability and social cognition via a machine learning assistant behavioral analysis toolbox- Social Behavioral Atlas (SBeA). Furthermore, S-ketamine exposure constantly activates microglia in the prefrontal cortex (PFC), mediating excessive synaptic pruning and dendritic structural abnormalities, leading to overexcitation of excitatory synaptic transmission. Notably, S-ketamine exposure activated Stat1-Arg1 pathway in microglia. Downregulating Arg1 expression or prophylactic administrating Arg1 selective inhibitor nor-NOHA could reverse microglial overactivation and attenuate the neurodevelopmental disturbance induced by S-ketamine exposure. Our study identifies the abnormal behavioral phenotypes in adolescence induced by early postnatal S-ketamine exposure and reveals a potential target for preventing anesthesia-related neurodevelopmental abnormalities.
