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
Sappanone A (SAP), a high-isoflavone compound derived from the traditional Chinese medicine Sumu, exhibits various pharmacological activities, including anti-inflammatory and anti-oxidant effects. However, its protective effects on the liver have rarely been reported. The aim of this study was to investigate the effects of SAP on immune-mediated liver injury induced by concanavalin A (Con A) in mice and to explore the underlying molecular mechanisms. Mice were administered SAP intraperitoneally (50 mg/kg body weight). Three hours later, Con A (18 mg/kg) was injected via the tail vein to induce liver damage. Livers and blood were collected 12 h after Con A challenge. Liver cell apoptosis, oxidative stress, and M1 macrophage activation in vivo were investigated. Bone marrow-derived macrophages were used to confirm the effects of SAP on M1 polarization in vitro. The results indicated that SAP decreased transaminase levels, inhibited apoptosis, and improved oxidative stress in mouse livers. Furthermore, SAP significantly reduced the proportion of macrophages, inhibited the expression of CD86, and downregulated the expression of M1 macrophage-related inflammatory cytokines. Moreover, SAP-treated macrophages alleviated liver damage caused by Con A compared to non-SAP-treated macrophages. Mechanistically, SAP inhibited the phosphorylation of key molecules in the MAPK and NF-κB signaling pathways in macrophages, resulting in an inhibitory effect on M1 macrophage activation. Taken together, SAP alleviates immune-mediated liver injury induced by Con A by suppressing M1 macrophage polarization, which is partially associated with NF-κB and MAPK signaling pathways.
