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

The polyphagous corn earworm Helicoverpa zea relies on cytochrome P450 monooxygenases with broad substrate specificities to cope with the wide diversity of phytochemicals it encounters among its numerous host plants. These enzymes also contribute to the ability of this insect to tolerate toxins from sources other than its hosts, including microbial and synthetic toxins. Although upregulation of xenobiotic-metabolizing P450s in some herbivorous insects is closely linked to host plant toxins, transcriptional and/or post-transcriptional regulation of detoxification in this polyphagous species also appears to be relatively unspecialized. Reverse transcription polymerase chain reaction and metabolic analyses indicate that rare and infrequently encountered phytochemicals, as well as synthetic substances, can enhance metabolic activity in an adaptive fashion against both natural and synthetic toxins.
