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
Herein, the study was conducted to elucidate the impact of a rare sugar complex (RSC) containing L-arabinose, D-mannose, D-xylose, D-allulose, and D-tagatose on cognitive impairment in a Type 2 diabetes mellitus (T2DM) mouse model. Specifically, a diabetes model was established by administering a high-fat diet (HFD) followed by streptozotocin injection. Behavioral performance in T2DM mice was assessed using multiple behavioral tests, including the Morris water maze, Y maze, novel object recognition test, and novel location recognition test. Neuronal damage in the hippocampal region was detected through hematoxylin and eosin staining. Superoxide dismutase (SOD) and malondialdehyde (MDA) constituted key biomarkers for assessing oxidative stress, with SOD indicating antioxidant capacity and MDA reflecting lipid peroxidation. Both were quantified via enzyme-linked immunosorbent assay. Additionally, the types and richness of microorganisms in the feces of each group of mice were analyzed through 16S sequencing of gut microbiota. Behavioral assays demonstrated that T2DM mice exhibited learning and memory impairments, which were notably mitigated by the administration of RSC. SOD activity decreased significantly, whereas MDA levels increased substantially. HE staining revealed that RSC effectively suppressed hippocampal cell apoptosis in T2DM mice. Furthermore, RSC treatment restored the diversity and abundance of gut microbiota in T2DM mice. Collectively, these findings suggest that RSC alleviates cognitive impairment in T2DM mice by reducing cerebral oxidative stress and modulating the intestinal microbiome composition.
