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

The interplay between food components and gut microbiota has been considered an important factor affecting the functionality of health-promoting foods. In this study, the effects of the probiotic Lactobacillus paracasei A221 on the functionality and bioavailability of kaempferol-3-o-sophroside (KP3S), a kaempferol-glucoside contained in kale, were investigated in vitro and in vivo. Unlike the type strain NBRC15889, the A221 strain converted standard KP3S as well as the kaempferol-glucosides in kale extract into kaempferol (KP). Using an intestinal barrier model, treatment with A221 significantly improved the effects of kale extract on the barrier integrity in vitro. KP, but not KP3S, clearly induced similar effects, suggesting that KP contributes to the functional improvement of the kale extract by A221. Pharmacokinetics analyses revealed that the co-administration of A221 and KP3S significantly enhanced the amount of deconjugated KP in murine plasma samples at 3 h post-administration. Finally, the oral administration of KP to Sod1-deficinet mice, which is a good mouse model of age-related disease, clearly ameliorated various pathologies, including skin thinning, fatty liver and anemia. These findings suggest that Lactobacillus paracasei A221 is effective for enhancing the anti-aging properties of kaempferol-glucosides by modulating their functionality and bioavailability through the direct bioconversion.
