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

Lipochitooligosaccharides (LCOs) are plant growth regulators that promote at subfemtomolar concentrations cell division in tobacco protoplasts. In response to LCO treatment, tobacco cells release a second growth factor that fully mediates the growth-promoting activities of the initial extracellular LCO stimulus. This diffusible growth factor was isolated from the protoplasts' culture filtrate and shown to be a peptide. We report that the LCO-induced mitogen released by tobacco cells and a synthetic heptadecapeptide derived from region 2 of the tobacco homolog of the early nodulin gene ENOD40 are antigenically related and qualitatively indistinguishable in their ability to stimulate cell division.
