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

Mounting evidence thus far indicates that human cytochrome P450 2B6 (CYP2B6), an enzyme expressed at a relatively low level functionally, is primarily responsible for the metabolism of several clinically relevant drugs, including propofol, efavirenz, bupropion, mephobarbital, and the propofol analog 2,6-di-sec-butyl phenol. We used molecular dynamics and molecular docking methods to predict such interactions and to compare with experimentally measured metabolisms. Insight II and Discover Studio 2.5 were used to carry out the docking of these substrates into CYP2B6 to explore the critical residues and interaction energies of the complexes. Phe297, Glu301, Thr302 and Val367 were identified as major drug-binding residues, which is consistent with previous data on site-directed mutagenesis, crystallography structure, and from modeling and docking studies. In addition, our docking results suggest that nonpolar amino acid clusters and heme also participate in binding to mediate drug oxidative metabolism. The binding modes of the five clinically relevant substrates mentioned above for metabolism on CYP2B6 are presented.
