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

Naringenin, an initial synthesized flavanone in various plant species, is further utilized for production of many biologically active flavonoids, e.g., apigenin, eriodictyol, and genistein, by various plant enzymes including cytochrome P450s (P450s or CYPs). We examined how these flavonoids are oxidized by human P450 family 1 and 2A enzymes. Naringenin was principally oxidized at the 3'-position to form eriodictyol by CYP1 enzymes more efficiently than by CYP2A enzymes, and the resulting eriodictyol was further oxidized to two penta-hydroxylated products. In contrast to plant P450 enzymes, these human P450s did not mediate the desaturation of naringenin and eriodictyol to give apigenin and luteolin, respectively. Apigenin was oxidized at the C3' and C6 positions to form luteolin and scutellarein by these P450s. CYP1B1.1 and 1B1.3 had high activities in apigenin 6-hydroxylation with a homotropic cooperative manner, as has been observed previously in chrysin 6-hydroxylation (Nagayoshi et al.,
