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

Fucoidan, a fucose-rich polysaccharide from brown algae, has been used for transdermalformulations targeting inflammatory skin conditions, for the treatment of thrombosis, vascularpermeability diseases, subcutaneous wounds, and burns. However, the pharmacokinetics offucoidan after topical application has not been described. In this study, an ointment (OF)containing 15% fucoidan was topically applied to rats at the doses of 50-150 mg/g. The anti-Xaactivity was selected as the biomarker, and the amidolytic assay method was validated and appliedfor pharmacokinetic studies of fucoidan. Fucoidan in OF penetrated the skin and distributed intothe skin, striated muscle, and plasma with AUC0-48 = 0.94 μg·h/g, 2.22 μg·h/g, and 1.92 μg·h/mL,respectively. The longest half-life for fucoidan was observed in plasma, then in striated muscle andskin. It was found that the pharmacokinetics of fucoidan after topical OF application was linear, inthe range of 50-150 mg/kg. No accumulation of fucoidan in plasma was observed after repeatedtopical applications of 100 mg/kg during five days. Our results support the rationality of topicalapplication of formulations with fucoidan.
