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
Given ketamine's conflicting impacts on the central nervous system, investigating its effects within an inflammatory context becomes crucial. This study aimed to assess the impact of varying ketamine doses on neurotrophin and inflammatory cytokine levels within the brains of rats submitted to the sepsis model. Wistar rats were submitted to the cecal ligation and puncture (CLP) model of sepsis. Intraperitoneal ketamine injections (5, 15, or 25 mg/kg) or saline were administered daily for seven days, thirty days post-CLP. Rats were euthanized thirty minutes following the last injection for analysis of IL-1β, IL-6, IL-10, TNF-α, BDNF, NGF, NT-3, and GDNF levels in the frontal cortex, hippocampus, and striatum. CLP-induced elevated IL-1𝛽, IL-6, IL-10, and TNF-α levels in the frontal cortex and hippocampus of rats, with reduced BDNF levels across all structures examined. Furthermore, reduced NGF and GDNF levels were observed solely in the hippocampus. Ketamine at 5 mg/kg normalized CLP-induced alterations and, in Sham animals, increased BDNF and NGF levels in the frontal cortex and/or hippocampus. At 15 mg/kg, ketamine elevated BDNF and NGF levels in Sham animals, while at 25 mg/kg, it exacerbated the inflammatory response initiated by CLP. These findings suggest variable effects of ketamine within a context of systemic inflammation, emphasizing the importance of considering individual inflammatory backgrounds when utilizing ketamine.
