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

objectivesScutellaria baicalensis has been a subject of research interest due to its potential multiple therapeutic benefits. This study was to examine the distribution of baicalein, wogonin, oroxylin A and their glucuronide/sulfate-conjugated metabolites in plasma, colon, small intestine, lung, liver, pancreas, kidney, and prostate tissues and in pancreatic tumor in a xenograft animal model. In addition, we examined metabolic stability of baicalin in these tissues.

methodsA mouse xenograft model was prepared by injection of 3 × 10 human pancreatic cancer MiaPaCa-2 cells subcutaneously into nude mice. Mice were randomly allocated to control diet (AIN-76A) and 1% S. baicalensis diet (n = 8 per group) for 13 weeks. Levels of baicalein, wogonin, oroxylin A, and their conjugates in mouse tissues were measured by high-pressure liquid chromatography after enzymatic hydrolysis and then extraction.

resultsA substantial amount of baicalin (34%-63%) was methylated to oroxylin A and its conjugates in various organs during absorption. Whereas plasma contained predominantly conjugates of baicalein, wogonin, and oroxylin A, both aglycones and conjugates were found in all other tissues investigated and in tumor.

conclusionsSubstantial accumulation of bioactive metabolites are found in target tissues, suggesting strong potential for S. baicalensis use as a preventive or adjuvant supplement for pancreatic cancer.
