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
The effects of zearalenone (ZEA), a fungal toxin in food and feed, remain unclear on the mammary gland and lactation. This study examines ZEA-induced damage in lactating mice and bovine mammary epithelial cells (MAC-T), focusing on the role of the phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) pathway in regulating cell proliferation and apoptosis. The results demonstrated that exposure to ZEA at different doses (5 mg/kg, 10 mg/kg, and 20 mg/kg) reduced lactation in female mice and slowed weight gain in their offspring. Hematoxylin and eosin (HE) staining and CSNK immunofluorescence staining of mammary tissue confirmed ZEA-induced mammary gland damage in vivo. Further analysis using PCNA immunohistochemistry and fluorescent TUNEL staining revealed that ZEA promoted apoptosis and decreased the proliferative capacity of mammary tissues. In vitro, 20 μM ZEA decreased MAC-T cell proliferation, increased apoptosis and oxidative stress, inhibited PI3K/AKT signaling, and decreased κ-casein (CSNK) expression. Pretreatment with a reactive oxygen species (ROS) scavenger (NAC) or PI3K/AKT activator (740-Y-P) reversed these effects, with NAC specifically restoring PI3K/AKT activity inhibited by ZEA. Overall, this study concludes that ZEA induces MAC-T cell apoptosis and disrupts proliferation via the ROS-mediated PI3K/AKT pathway, ultimately impairing lactation function. These findings highlight potential targets for managing ZEA contamination in food and its impact on lactation.
