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

BACKGROUND AND

objectivesMyricetin is a flavonoid compound that is abundant in teas, red wine, berries, herbs and vegetables with a variety of pharmacological properties such as antioxidant, anti-inflammatory and anti-cancer effects. Although there are in vitro studies showing that myricetin inhibits human cytochrome P450 (CYP) 2D6 and CYP3A, the inhibitory mechanisms of myricetin on CYP enzymes are still unclear. The aim of this study was to evaluate the inhibitory effects of myricetin on human and rat CYPs, including CYP3A2/3A4, CYP2B1/2B6, CYP2C9/2C11 and CYP2D1/2D6.

methodsThis study was performed to investigate the inhibitory effects of myricetin on human CYP3A4, CYP2B6, CYP2C9, CYP2D6 and rat CYP3A2, CYP2B1, CYP2C11, CYP2D1 through the cocktail approach using ultra-performance liquid chromatography tandem mass spectrometry. Typical probe substrates were used as follows-midazolam for CYP3A2/3A4, dextromethorphan for CYP2D1/2D6, tolbutamide for CYP2C9/2C11, and bupropion for CYP2B1/2B6.

resultsThe results of this study showed that myricetin might not be a time-dependent inhibitor. Moreover, myricetin inhibited CYP3A4 in an uncompetitive way with an inhibition constant (K

conclusionsIn conclusion, this study indicates that myricetin inhibited CYP3A4/3A2, CYP2C9/2C11, CYP2D6/2D1 and CYP2B1 by various mechanisms with different K
