1 · What the graph read from it

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.

2 · The registry

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

This research systematically compared the jejunum morphology, antioxidant capacity, barrier-related gene expression, and mucosal immune status between two Yunnan local pig breeds, namely Dahe pigs (DH) and Dahe black pigs (DHB), using histopathological staining, antioxidant assays, quantitative polymerase chain reaction (qPCR), immunofluorescence, and enzyme-linked immunosorbent assay (ELISA). The outcomes indicated that DHB presented a shallower crypt depth and a higher ratio of villus height to crypt depth, suggesting an enhanced capacity for nutrient absorption. In their jejunum, the activities of glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) were significantly elevated, whereas the levels of malondialdehyde (MDA) were notably reduced. Conversely, DH displayed superior barrier function, with significantly higher expression levels of tight-junction proteins (Occludin,
