Detoxification of the solanaceous phytoalexins rishitin, lubimin, oxylubimin and solavetivone via a cytochrome P450 oxygenase.

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.
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
Solanaceous plants produce sesquiterpenoid phytoalexins to defend themselves against a variety of pathogens. These toxic compounds are not only harmful to the pathogen but also to the plant, and thus need to be detoxified by the plant after the threat has been eliminated. We report that the detoxification of rishitin, the major phytoalexin in potato tubers and tomato fruits, is mediated by a cytochrome P450 CYP76 family enzyme via the hydroxylation of the isopropenyl group resulting in the formation of 13-hydroxyrishitin, also known as rishitin-M1. We further observed hydroxylation of the potato phytoalexins solavetivone, lubimin and oxylubimin by the same enzyme. Constitutive expression of CYP76 in
