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
Purpose: Knee osteoarthritis (KOA) has been linked to increased cognitive decline risk, but the specific mechanisms underlying this phenomenon remain unclear. Research suggests neuroimaging changes and chronic low-grade inflammation may play key roles as common pathways linking osteoarthritis (OA) to cognitive decline. Patients and Methods: This cross-sectional study recruited 36 individuals diagnosed with KOA and 25 healthy controls (HCs). Cognition was assessed using the Montreal Cognitive Assessment (MoCA) and the Digit Cancellation Test (DCT). The gray matter volume of 12 hippocampal subfields and the serum TIM-3 levels were also measured. Results: KOA patients had significantly lower MoCA scores ( Conclusion: The hippocampal tail and hippocampal fissure exhibited reduced volume in KOA patients, and these changes were associated with alterations in attention and serum TIM-3 levels, respectively. These findings suggest a potential link between KOA and cognitive decline through inflammation and neuroscience, offering a theoretical basis for further study. Meanwhile, serum TIM-3 and right hippocampal fissure/tail volume might be potential biomarkers for detecting cognitive decline in KOA patients. Further studies are necessary for the investigation of this possibility.
