Ketamine induced gut microbiota dysbiosis and barrier and hippocampal dysfunction in rats.
Article in iScience, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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 microbiota-gut-brain axis (MGBA) plays a pivotal role in drug addiction. However, the pathophysiological mechanism of MGBA in ketamine addiction remains elusive. The present study investigated the ketamine-induced gut microbiota disorders, intestinal barrier dysfunction, and the alterations in brain function, using a conditioned place preference (CPP) model of ketamine addiction in rats. Compared with the control group, ketamine induced decreased amplitude of low-frequency fluctuation (ALFF) values in the hippocampus, and pyknotic nuclei and concentrated cytoplasm in hippocampal neurons, as well as alterations in gut microbiota composition, shortened ileum villi, and thinner colonic mucosa. We also found that the abundance of gut microbiota exhibited correlations with CPP score, hippocampal ALFF value, length of ileum villi, and thickness of colonic mucosa. Our findings provide evidence for abnormal alterations in the MGBA of ketamine-addicted rats, which improves our understating of the mechanism of ketamine addiction and the potential for developing new therapeutic strategies.
