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
Post-breeding endometrial inflammation is a well-known physiological response in jennies, especially after artificial insemination with frozen-thawed sperm. Bioactive molecules present in reproductive fluids, including cytokines, may contribute to regulating these immune processes. The aim of this study was to characterize the cytokine profile of preovulatory follicular fluid (FF) and seminal plasma (SP) in donkeys and to explore their potential relevance for reproductive physiology. To this end, 10 FF samples were collected from five fertile Catalan jennies, and 10 samples were isolated from 10 different Catalan jackasses' ejaculates. Cytokine concentrations were measured using a Luminex MagPix system with an equine-specific Milliplex MAP panel. Three cytokines were detected in the FF, with IP-10 being the most abundant, followed by IL-10 and eotaxin. The SP, in contrast, showed a broader cytokine profile, with 10 detectable mediators. Fractalkine was the most abundant cytokine in this biofluid, followed by FGF-2 and G-CSF. GRO and IL-1β were present at intermediate concentrations, and IL-8, IL-13 and IL-12 were observed at low concentrations. From the 10 cytokines detected, IP-10 and eotaxin were found at the lowest concentrations. These results provide the first description of cytokines in donkey FF and SP. The presence of chemotactic and immunomodulatory cytokines in these reproductive fluids suggests they may contribute to the regulation of follicular processes and the post-breeding inflammatory response in jennies.
