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

Expression of a dominant inhibitor of the Dictyostelium cAMP-dependent protein kinase in prespore cells blocks their differentiation into spore cells. The resultant structures comprise a normal stalk supporting a bolus of cells that fail to express a sporulation-specific gene and that show greatly reduced levels of expression of several prespore-specific genes. The latter result suggests that in addition to activating spore formation, the cAMP-dependent protein kinase may play a role in initial prespore cell differentiation. Development of the strain expressing the dominant inhibitor is hypersensitive to the inhibitory effects of ammonia, the molecule that is believed to repress entry into culmination during normal development. This result supports a model whereby a decrease in ambient ammonia concentration at culmination acts to elevate intracellular cAMP and hence induce terminal differentiation.
