Absorption-Enhancing Mechanisms of Capryol 90, a Novel Absorption Enhancer, for Improving the Intestinal Absorption of Poorly Absorbed Drugs: Contributions to Trans- or Para-Cellular Pathways.
Article in Pharmaceutical research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeWe have previously reported that Capryol 90 improves the intestinal absorption of insulin, a peptide drug, without causing serious damage to the intestinal epithelium. However, the effects of Capryol 90 and its related formulations on the intestinal absorption of other drugs, and their absorption-enhancing mechanisms are still unclear. The aim of this study is to evaluate the effects of Capryol 90 and its related formulations on the intestinal absorption of drugs and elucidate their absorption-enhancing mechanisms.
methodsThe intestinal absorption of 5(6)-carboxyfluorescein, fluorescein isothiocyanate-dextrans, and alendronate was evaluated using an in situ closed loop method. Brush border membrane vesicles (BBMVs) were labeled with fluorescent probes, and the fluidity of membrane was evaluated by a fluorescence depolarization method. The expression levels of tight junction (TJ) proteins were measured using a Western blot method and immunofluorescence staining.
resultsAmong the tested excipients, Capryol 90 significantly improved the small and large intestinal absorption of drugs. In mechanistic studies, Capryol 90 increased the membrane fluidity of lipid bilayers in BBMVs. Additionally, Capryol 90 decreased the expression levels of TJ-associated proteins, namely claudin-4, occludin, and ZO-1.
conclusionsCapryol 90 is an effective absorption enhancer for improving the intestinal absorption of poorly absorbed drugs via both transcellular and paracellular pathways.
