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
Background: Obesity, a rising global health issue, is linked to numerous disorders, including cognitive impairment. Objectives: This study investigates the effects of coenzyme Q10 (Co-Q10) on cognitive performance, antioxidant defense, cholinergic activity, and hippocampal neuron damage in rats rendered obese by monosodium glutamate (MSG) exposure. Methods: Forty-eight neonatal male Wistar rats were randomly assigned to one of four groups: Control, MSG, MSG + Q10-10, and MSG + Q10-20. Monosodium glutamate (4 g/kg BW) was administered subcutaneously into the cervical region from postnatal day (PND) 2 to PND 10. Coenzyme Q10 (10 mg/kg BW and 20 mg/kg BW) was administered intraperitoneally from PND 30 to PND 42. At the end of the treatment period, working memory and avoidance learning tests were conducted. Anthropometric data were collected, followed by evaluations of hippocampal catalase (CAT), superoxide dismutase (SOD), acetylcholinesterase (AChE), glutathione peroxidase (GPx), and malondialdehyde (MDA) levels. The density of apoptotic/dark neurons (DN) in the CA₁ and CA₃ regions of the hippocampus was also assessed. Results: Monosodium glutamate treatment increased Body Mass Index (BMI) and Lee Index, impaired working memory and avoidance learning, and reduced CAT, SOD, and GPx activities. Additionally, MSG exposure led to elevated MDA levels, increased AChE activity, and higher DN density in the CA₁ and CA₃ hippocampal regions. Treatment with Co-Q10 resulted in a decrease in BMI, enhanced memory and learning, noteworthy increases in CAT, SOD, and GPx activities in the hippocampus, and reductions in MDA levels, AChE activity, and DN density in the CA₁ and CA₃ regions. Conclusions: Coenzyme Q10 mitigates hippocampal neuronal damage and improves cognitive function in MSG-induced obesity, primarily through its antioxidant and AChE inhibitory properties.
