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
purposeSulfated galactofucan (SWZ-4), which was extracted from Sargassum thunbergii, has recently been reported to show anti-inflammatory and anticancer properties. The present study aimed to evaluate whether SWZ-4 attenuates atherosclerosis in apolipoprotein E-knockout (ApoE-KO) mice by suppressing the inflammatory response through the TLR4/MyD88/NF-κB signaling pathway.
methodsMale ApoE-KO mice were fed with a high-fat diet for 16 weeks and intraperitoneally injected with SWZ-4. RAW246.7 cells were treated with lipopolysaccharide (LPS) and SWZ-4. Atherosclerotic lesions were measured by Sudan IV and oil red O staining. Serum lipid profiles, inflammatory cytokines, and mRNA and protein expression levels were evaluated.
resultsSWZ-4 decreased serum TNF-α, IL-6 and IL-1 levels, but did not reduce blood lipid profiles. SWZ-4 downregulated the mRNA and protein expression of TLR4 and MyD88, reduced the phosphorylation of p65, and attenuated atherosclerosis in the ApoE-KO mice (p < 0.01). In LPS-stimulated RAW 264.7 cells, SWZ-4 inhibited proinflammatory cytokine production and the mRNA expression of TLR4, MyD88, and p65 and reduced the protein expression of TLR4 and MyD88 and the phosphorylation of p65 (p < 0.01).
conclusionThese results suggest that SWZ-4 may exert an anti-inflammatory effect on ApoE-KO atherosclerotic mice by inhibiting the TLR4/MyD88/NF-κB signaling pathway in macrophages and therefore may be a treatment for atherosclerosis.
