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 AlcR fungal protein responds to ethanol and binds to the fungal pAlcA promoter in its presence. This system was transferred to plants over twenty years ago and was claimed to function in the same manner in plants. However, never has the control experiment with plants containing the AlcR gene alone, with no downstream inducible construct, been made. In this paper, I conduct several experiments with this control, growing p35:AlcR plants in the presence or absence of ethanol. I found that when these plants were grown in the presence of ethanol, growth in several tissues and several stages of growth was retarded. This demonstrates that this system is not suitable for use in the plant sciences, and casts doubt on the conclusions of papers that have published phenotypes using this system.
