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

objectivesTriptolide is an active component derived from Tripterygium wilfordii and it possesses numerous pharmacological activities. However, it remains unclear how triptolide influences the activity of human liver cytochrome P450 (CYP) enzymes and P-glycoprotein (P-gp).

methodsIn this study, the inhibitory effects of triptolide on the eight human liver CYP isoforms (i.e., 1A2, 3A4, 2A6, 2E1, 2D6, 2C9, 2C19, and 2C8) were investigated in vitro using human liver microsomes (HLMs), and the effects of triptolide on the activity of P-gp were investigated using a rhodamine-123 uptake assay.

resultsThe results showed that triptolide inhibited the activity of CYP1A2 and CYP3A4, with 50 % inhibitory concentration (IC

conclusionsThe in vitro studies of triptolide with CYP isoforms and P-gp indicate that triptolide has the potential to cause pharmacokinetic drug interactions with other co-administered drugs metabolized by CYP1A2 and CYP3A4. Further clinical studies are needed to evaluate the significance of this interaction.
