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

This report presents quantitative measurements of cell area and motility on the time scale of seconds. The response of Dictyostelium discoideum amoebae to step changes in chemoattractant concentration were followed using an image-processing system. Parameters reflecting total area and motility of several hundred to thousand cells were measured with a time resolution of 2.5 s. Responses of growth phase cells to folate and of starved cells to cAMP were similar. An increase in chemoattractant concentration produced a brief increase in motility followed by a longer-lasting decrease that returned to initial values in 90 s. At high cAMP concentrations the motility remained depressed. Area also increased transiently. Half-maximal responses were produced by 2 nM folate or 2 nM cAMP. Removal of chemoattractant produced a temporary increase in motility and decrease in area. These responses support a model in which antagonistic signals are used to orient cell movement.
